Changing Employers on H-1B: Portability, Start Dates, Travel and Pending Petitions

The quick answer

Yes — but not because the petition was filed, and not necessarily on the day it was filed.

You may begin work for the new employer before USCIS decides the petition only if you meet the portability conditions, and then only from the later of two dates: the day a non-frivolous petition was properly filed for you, or the start date that petition asked for.

Start before that date, or without meeting the conditions, and you are working without authorisation.

Under the current portability regulation, an eligible H-1B worker is authorised to begin new or concurrent employment upon the filing of a non-frivolous H-1B petition, in accordance with the filing rules, or as of the requested start date, whichever is later (8 CFR 214.2(h)(2)(i)(H) ↗).

Three words in that sentence do work: eligible, non-frivolous, and in accordance with the filing rules. Drop any of them and the rule stops being true.

You do not have to wait for final USCIS approval merely because you are changing employers. And issuance of the physical USCIS receipt notice is not itself the legal start trigger — but read section 5 before you rely on that, because a filing that is rejected never had a filing date at all.

That means the useful question is not:

"Has my transfer been sent?"

It is:

"Was a non-frivolous petition properly filed, am I eligible for portability, and has the requested start date arrived?"

1. What people call an H-1B "transfer" is a new petition

There is no immigration document that transfers Employer A's H-1B petition to Employer B.

Employer B petitions for the H-1B employment it wants you to perform. That normally means a Form I-129 H-1B petition supported by the required documentation, including an appropriate certified Labor Condition Application covering the employment.

The LCA and the H-1B petition are not the same thing.

A certified LCA is an important part of Employer B's case. It addresses labour-condition requirements including wages and working conditions. But certification of the LCA does not itself authorise you to start working for Employer B.

Nor does an offer letter.

2. Who qualifies for H-1B portability?

This is where the slogan "H-1B transfer" becomes dangerous.

The rule does not say that anyone who already holds an H-1B can start with another employer. The regulation sets out these conditions (8 CFR 214.2(h)(2)(i)(H)(1) ↗):

you were lawfully admitted to the United States in, or otherwise provided, H-1B status;

a non-frivolous H-1B petition for new employment — including a petition for new employment with the same employer — was filed on your behalf, with the required request to amend or extend your stay, before your period of stay expired; and

you have not worked without authorisation in the United States from your relevant last admission through the filing of the new petition.

Two details are easy to miss.

"Including a petition for new employment with the same employer." Portability is not only for moves between companies. A materially different role with your current employer can be a portability event.

"Period of stay authorized by the Secretary" is not the same as your I-94 date. The regulation uses that phrase deliberately, and elsewhere in the same rule it treats a worker with a timely portability filing as being in an authorised period of stay even after the I-94 date passes (8 CFR 214.2(h)(2)(i)(H)(3)(i) ↗). Read carefully: that provision is about eligibility to file the next petition, not about being admitted at an airport. Do not turn it into a reason to travel on an expired I-94.

Two engineers with identical offers from the same company can have different start-date answers because their I-94s, admission histories and intervening filings are different.

3. When can you actually start with Employer B?

Meet Rohan.

Rohan is an H-1B software engineering manager working for Employer A. Employer B offers him a new role beginning October 15, prepares the LCA, and files the H-1B petition.

Suppose Employer B properly files on October 5.

Can Rohan start on October 5?

Not if Employer B requested October 15 as the employment start date. The regulation uses the later of two events: proper filing of the non-frivolous petition, or the requested start date. In that example the portability start date cannot precede October 15.

Now change the facts. Employer B requests October 1 and files on October 5. The later event is October 5.

"Start when filed" is an incomplete version of the rule.

4. Do you need the USCIS receipt notice before starting?

Not as the legal trigger. The regulation ties portability to the filing and the requested start date, whichever is later. It says nothing about Form I-797.

We checked this the hard way, because it is the kind of claim that sounds right and often is not. The words "receipt notice", "Notice of Action" and "I-797" appear nowhere in the filing rules or on the USCIS H-1B page.

Here is the proof that this is deliberate rather than an oversight. In the H-2B rules, the government does key a deadline to the paper notice, in terms: it counts from "the Received Date on Form I-797 (Notice of Action)" (8 CFR 214.2(h)(31)(ii)(A) ↗). The government says so when it means it. For H-1B portability it did not.

But there is a distinction between the legal rule and proving you satisfied it.

A receipt notice is strong evidence that USCIS received and accepted a filing. Employers may reasonably wait for it before putting you on payroll. That is a risk-control decision, not the rule.

So neither shortcut is safe:

"FedEx delivered it, so I can definitely start."

or

"I cannot legally start until the receipt notice arrives."

Establish the actual filing position. And read the next section before you treat a courier record as a filing.

5. Rejected is not the same as denied

This distinction deserves attention before you resign.

A denial happens after USCIS accepts a petition and adjudicates it.

A rejection is different. Under the filing rules, a benefit request that is rejected does not retain a filing date (8 CFR 103.2(a)(7)(ii) ↗).

That is what makes rejection so dangerous in a portability case. Portability rests on a filing. If the filing was rejected, there was never a filing date for portability to attach to — and you may have resigned on the strength of a courier's delivery record.

Current form edition, signature, required fees and filing location all matter.

This does not mean every worker must wait for a receipt notice. It means you should know what Employer B and its counsel are relying on before choosing the day you stop working for Employer A.

6. What happens if Employer B's petition is decided?

Note the heading. Not "denied" — decided.

The regulation says portability employment authorisation ceases upon the adjudication of the petition (8 CFR 214.2(h)(2)(i)(H)(2) ↗). That means any decision, including an approval. The statute and the work-authorisation rules use the same word.

Read alone, that sentence could make someone whose petition was just approved stop working. So here is the other half, in USCIS's own words: if the new petition is approved, you may continue working for the new employer for the period of time shown on the approval notice. The approved petition takes over from portability. Nothing is interrupted.

If USCIS denies the petition, you cannot keep working for Employer B on the theory that portability once existed.

What happens next depends on the rest of your record: whether another approved H-1B remains usable, whether another petition is pending, whether your I-94 remains valid, and whether an independent basis for authorised employment or stay exists.

Understand that downside before you leave Employer A.

7. What if Employer A lets you go before Employer B files?

Then another clock starts.

Certain employment-based nonimmigrants, including H-1B workers, are not treated as having failed to maintain status solely because the employment ended — for up to 60 consecutive days or until the end of the authorised validity period, whichever is shorter, once during each authorised validity period (8 CFR 214.1(l)(2) ↗).

Do not translate that into "everyone gets 60 days."

Three limits sit in the same sentence. DHS may eliminate or shorten the period as a matter of discretion. The period cannot run past your authorised validity period. And the regulation states plainly that, unless separately authorised, the worker may not work during it. That is stronger than saying it "does not authorise" work — it is a prohibition.

Someone in that position may, if otherwise eligible, seek an extension of stay or a change of status (8 CFR 214.1(l)(3) ↗). That is why a timely Employer B filing can be critical after a termination.

One search tip, because it costs people hours: the regulation never uses the phrase "grace period." The heading is "Period of stay". If you search for "grace period" in the rules you will not find it.

A September 2026 currentness warning. DHS has proposed removing this 60-day period (Federal Register, 11 September 2026 ↗), with comments closing 10 November 2026. That is a proposal, not current law as of 24 September 2026. The existing regulation remains operative unless and until the rulemaking changes it — and because this is live, check it before you rely on it.

SOSGI's H-1B layoff guide remains the place for the full playbook. The employer-change lesson is narrower: if Employer A has already ended your employment, calculate the filing window from your actual immigration dates, not from an assumption that you have two months.

8. Do you need the H-1B lottery again?

Sometimes no. Sometimes yes — and getting that distinction wrong can stop the new employer filing a cap-subject petition when you expect them to.

If you have already been counted. A worker counted against the cap within the six years before the new petition is approved is not counted again — unless that worker would be eligible for a full new six years of H-1B admission at the time the petition is filed (INA 214(g)(7), 8 U.S.C. 1184(g)(7) ↗). A registration is required only for someone who may be counted (8 CFR 214.2(h)(8)(iii)(A)(1) ↗).

Notice where the exception bites: someone who has been outside the United States for a year or more may fall inside that "unless", because they would be eligible for a fresh six years. If that is you, do not assume a routine move.

The cap-exempt line is where people are caught. If your cap-exempt H-1B employment ends and you are not the beneficiary of a new cap-exempt petition, you will be subject to the cap unless you were previously counted within the six-year period of authorised admission your cap-exempt employment applied to (8 CFR 214.2(h)(8)(iii)(F)(5) ↗).

Read that again: will, not may. If you have spent four years at a university and were never in a lottery, a private-sector employer cannot simply file for you. They need a selected registration first. The same provision adds that where cap-exempt employment converts to cap-subject employment, USCIS may revoke the petition.

Holding both jobs at once. A worker in valid cap-exempt H-1B status may hold concurrent cap-subject H-1B employment without being counted against the cap (8 CFR 214.2(h)(8)(iii)(F)(6) ↗). The cap-subject petitioner must show three things: that you are in valid cap-exempt H-1B status; that the cap-exempt employment is expected to continue after the cap-subject petition is approved; and that you can reasonably and concurrently perform both jobs.

Two consequences are built into the same rule, and they are the ones to watch. The cap-subject approval cannot run past the validity of the cap-exempt employment. And if the cap-exempt job ends early — whether the employer ends it or it simply runs out — you become subject to the cap, and USCIS may revoke the cap-subject petition.

So the concurrent route is a bridge that stands on the cap-exempt job. Resign that job and the bridge goes with it.

Before crossing from a university, affiliated nonprofit or qualifying research organisation into ordinary private-sector employment, ask a separate question: have I previously been counted for the H-1B period I am using, or am I relying on cap-exempt employment?

Do not assume the word "transfer" answers it.

9. Can you work for Employer A and Employer B at the same time?

H-1B status is not necessarily limited to one employer.

The portability regulation expressly covers concurrent or new employment. A second employer can petition for authorised concurrent H-1B employment while the first continues.

But concurrent H-1B employment is not permission to freelance. Each employment relationship needs its own valid immigration basis.

10. What if Employer C appears while Employer B is still pending?

This is the "bridge petition" problem.

Suppose Rohan joins Employer B under portability. Employer B's petition is still pending. Employer C makes him another offer.

Successive portability petitions are permitted in qualifying circumstances (8 CFR 214.2(h)(2)(i)(H)(3) ↗). A second move is not automatically barred.

But the petitions are not independent islands, and the regulation is blunter than most explanations suggest.

The bar. If your previously approved H-1B status has expired while the chain is pending, and a required amendment or extension-of-stay request in an earlier petition is denied, the corresponding request in a later successive petition cannot be approved — with one exception, where the later petition independently establishes eligibility. That is a bar, not a risk.

The protection. Denial of a successive portability petition does not affect a worker's ability to continue or resume employment under an earlier approved petition — where the regulation's conditions are met. The regulation names three. Worth knowing before you rely on this: USCIS's own web page states only the first of the three. We are recording that gap rather than papering over it. If you are in this position, the regulation is the text to work from, and this is a situation for counsel.

So before moving A → B → C while B remains pending, map: last approved H-1B → current I-94 → B filing → B requested dates → C filing → the status of each extension request.

The chain matters.

11. Can you travel to India while the petition is pending?

Before you book a flight while any H-1B request is pending, get advice on your own case. Do not travel on the strength of a general article, including this one.

This section changed substantially in September 2026, and a great deal of advice still circulating online is now wrong.

Three things are established, and they are different from one another.

One. If the request pending for you is a change of status, leaving the country ends it. Since 15 September 2026 this is written into the regulations: if you file a change of status application on time but depart the United States while it is pending, USCIS will consider the application abandoned (8 CFR 248.1(f) ↗). This applies to every nonimmigrant category, H-1B included. The underlying petition can still be approved — but you would then generally need to obtain a visa at a U.S. embassy or consulate and be admitted afresh.

Two. If the request pending for you is an extension of stay rather than a change of status, we did not find a rule either way. We could not identify a current regulation or USCIS policy provision establishing that departure automatically abandons the extension request. Do not read that as permission. Older articles sometimes assert a broader rule, often relying on USCIS material that is now archived and marked out of date.

What is settled is narrower, and it is not reassuring. You must be physically present in the United States when the extension is filed. If you leave while it is pending, the State Department's guidance sends you to a consulate to apply for a visa before you can return (9 FAM 402.10-12 ↗). USCIS can also approve the petition and refuse the extension of stay in the same decision, and that refusal cannot be appealed (8 CFR 214.1(c)(7) ↗).

Three. There is an unresolved court fight over the $100,000 H-1B payment. The USCIS H-1B page ↗ still describes the payment, and a presidential proclamation issued on 18 September 2026 purports to extend the underlying entry restriction through September 2027.

But on 8 June 2026 the U.S. District Court for the District of Massachusetts vacated the policy implementing that payment in its entirety. On 24 July 2026 the U.S. Court of Appeals for the First Circuit refused the government's request to pause that judgment while its appeal runs (State of California v. Mullin, No. 26-1699). As of 24 September 2026 the vacatur stands and the appeal is still live.

So the government's own page and the courts do not currently agree. Do not rely on the USCIS page alone to decide whether the payment applies to you, and do not assume it is gone for good either. Check both the court position and the agency position immediately before you file or fly.

And if your visa has expired, add one more. You cannot be issued a new H-1B visa until the pending petition is approved (9 FAM 402.10-11(A) ↗). Leaving can strand you abroad indefinitely.

Analyse an India trip during an employer change as:

petition + extension request + visa + admission + new I-94

rather than:

receipt + flight.

12. Can you use an H-1B visa issued while you worked for Employer A?

An H-1B visa and an H-1B petition do different jobs.

Your visa is not cancelled because you changed employers. You can keep using the visa you already hold, as long as it is still valid — but you must carry proof of the new petition in addition to the visa: the dated filing receipt if the new petition is still pending, or the new Form I-797 approval notice once it has been approved (9 FAM 402.10-11(A) ↗).

That is not a suggestion. It is what the State Department's guidance says a returning worker must present.

Two limits matter.

A visa's expiry date is set by the petition it was issued on (22 CFR 41.53(c) ↗). A visa issued on Employer A's petition still runs out when that petition's dates said it would, whatever your new job says.

And if both your old visa and old petition have expired, you cannot be issued a new visa until the pending petition is approved. Leaving can leave you stuck.

So avoid the shortcut "old stamp + new receipt = definitely fine." Check the complete admission package.

One thing to raise before the petition is filed. If you already know you will be travelling, that changes what your employer should tick on the Form I-129. There is a specific box for a worker who is in the United States now but will leave to obtain a visa or be admitted abroad. That choice is made before filing, not after. Raise it with your employer early.

13. Your I-94 is part of the decision, not background paperwork

Before changing employers, retrieve your current Form I-94.

Do not rely only on the expiration date printed on an old I-797 approval notice. International travel can produce a later I-94, and the portability rules repeatedly turn on authorised stay and timing.

Compare: passport · latest I-94 · current H-1B approval · employment history · Employer B filing date · Employer B requested start date.

If those dates do not fit together the way you expected, resolve that before resigning.

14. What happens to your green-card case?

H-1B portability and employment-based green-card portability are different legal regimes. Changing H-1B employers does not transfer Employer A's PERM or immigrant petition to Employer B.

Going past six years on H-1B: two different routes, often confused.

Route one — the 365-day route. If at least 365 days have passed since a labour certification or an employment-based immigrant petition was filed for you, you may be granted H-1B time beyond six years, in increments of up to one year. Nothing has to be approved — filed is enough (8 CFR 214.2(h)(13)(iii)(D) ↗). One trap: you lose this if you do not apply for adjustment or an immigrant visa within one year of a visa becoming available in your category.

Route two — the per-country route. If you are the beneficiary of an approved EB-1, EB-2 or EB-3 petition and would be eligible for that status but for the per-country limit, you may be granted H-1B time in increments of up to three years, and your employer must show that unavailability as of the date the H-1B petition is filed (8 CFR 214.2(h)(13)(iii)(E) ↗).

The distinction is not academic. Route two turns on the per-country limit specifically — not on a general backlog. And route one needs no approval at all, which means people with pending cases often have a year available that they never ask for.

Two facts that help more people than they should: neither route requires the H-1B employer to be the one that filed your PERM or I-140. And if you hit the six-year wall with nothing filed, the rules require a full year physically outside the United States before H-1B or L status can resume.

Changing jobs with a pending I-485. If your I-485 has been pending 180 days or more and your I-140 is approved — or is pending and later approved, and its approval has not been revoked — the petition stays valid for a new job in the same or a similar occupational classification (8 U.S.C. 1154(j) ↗; 8 CFR 245.25 ↗).

Two things the short version leaves out, and both matter:

You must file Form I-485 Supplement J. This is a condition, not a formality. Porting on a phone call is not porting.

Not every employment-based petition is covered. This rule reaches employer-filed petitions in the EB-1B, EB-1C, EB-2 and EB-3 groups, and non-physician national-interest-waiver applicants can port. Some employment-based petitions sit outside it entirely (USCIS Policy Manual, Vol. 7, Part E, Ch. 5 ↗). Check which one your case rests on before you rely on this.

If your case is not in one of those groups, do not assume this rule protects it. What a job change does to your case then turns on the rules governing your own petition, not on this provision. Get that looked at before you resign, not after.

So if you have PERM, an I-140 or an I-485, put those documents on the table before leaving Employer A.

15. What happens to an H-4 spouse or children?

Employer B's petition is about the principal worker. It does not reset every family member's dates.

Review each dependent's passport · H-4 I-94 · H-4 approval notice · pending Form I-539, if any · EAD expiry, if applicable.

H-4 work permits are for spouses only. An H-4 child can never get one. That is not a technicality; it is the difference between a lawful job and unauthorised employment that follows a young adult into every future filing.

An H-4 spouse may be eligible only if the H-1B principal either:

is the beneficiary of an approved Form I-140; or

has H-1B time authorised under AC21 sections 106(a) and (b) — the 365-day route described in section 14.

Those two, and no others (8 CFR 214.2(h)(9)(iv) ↗; 8 CFR 274a.12(c)(26) ↗). Two further conditions sit in the same rule and are easy to miss: the principal must currently be in H-1B status, and the spouse must currently be in H-4 status.

Apply on Form I-765 under category (c)(26).

The employer change itself is not the H-4 EAD eligibility test. SOSGI's dedicated H-4/H-4 EAD guide remains the main guide for those rules.

Before you resign: Rohan's checklist

1. What is my latest I-94 expiration date?

2. Am I currently maintaining the position Employer B's filing relies on?

3. Is Employer B's certified LCA appropriate for the offered employment?

4. Has Employer B's petition actually been filed — and accepted, not rejected?

5. What start date did Employer B request?

6. Do I satisfy the portability conditions, including the non-frivolous requirement?

7. What happens if USCIS denies the petition?

8. Am I relying on a 60-day position after a termination?

9. Have I previously been counted against the cap — or does this move cross the cap-exempt line?

10. If I am leaving cap-exempt work, is there a new cap-exempt petition for me?

11. Is another portability petition already pending?

12. Am I travelling internationally before a decision — and is the pending request a change of status or an extension of stay?

13. Do I have PERM, I-140 or I-485 consequences, and is my category one that can port?

14. What are the current H-4 and EAD dates for every dependent?

That is a better resignation checklist than "my lawyer sent the transfer."

Eight H-1B sentences to distrust

"I can start as soon as the petition is filed." Incomplete. For an eligible worker, the rule uses proper filing of a non-frivolous petition or the requested start date, whichever is later.

"I have to wait for the receipt notice." Not as a legal rule. Receipt issuance is not the regulatory trigger — though receipt evidence matters operationally, and a rejected filing never had a filing date at all.

"FedEx says delivered, so my transfer is filed." Not necessarily. A rejected benefit request does not retain a filing date.

"My petition was approved, so I should stop working until the new dates start." No. Portability ends on adjudication, but an approval replaces it — you continue for the period shown on the approval notice.

"Everyone gets 60 days after a layoff." No. Up to 60 days or the remainder of the authorised validity period, whichever is shorter, subject to DHS discretion — and you may not work during it.

"Transfers never need the lottery." Too broad, and the exception matters. Leaving cap-exempt work without a new cap-exempt petition will make you cap-subject if you were never counted.

"I can't move again until Employer B's petition is approved." Not categorically. Successive portability petitions are permitted — but if your approved status has expired, an earlier denial can bar the later request.

"My H-1B transferred, so my green card transferred too." No. They are separate regimes — and not every green-card category can use the job-change rule at all.

FAQ

Can I start with Employer B before USCIS approves the petition? If you satisfy the portability requirements, yes — beginning on proper filing of a non-frivolous petition or the requested start date, whichever is later.

Do I need the physical receipt notice? Not as the legal trigger. But you need confidence that there was a qualifying, accepted filing, and the receipt notice is the best evidence of it.

Can I resign before Employer B files? You can, but it can materially change the analysis. If Employer A employment ends before Employer B files, the 60-day, authorised-stay and I-94 rules become central.

What if Employer B's filing is rejected? A rejected request does not retain a filing date. That is materially different from a petition USCIS accepts and later denies — and it means portability never started.

What if the petition is denied after I have already started? Portability authorisation cannot continue past adjudication. Your position then depends on your remaining approved status, I-94, other petitions and history.

What if it is approved? You continue working for the new employer for the period shown on the approval notice. Nothing is interrupted.

Can I change employers again while Employer B's petition is pending? Qualifying successive portability petitions are permitted. But if your previously approved status has expired, a denial earlier in the chain can bar the later extension request.

Can I travel to India while the employer-change petition is pending? Treat this as the highest-risk question in the guide, and get advice on your own case. If the pending request is a change of status, departure now abandons it by regulation. If it is an extension of stay, we found no rule either way — which is not the same thing as permission. And leaving on an expired visa can strand you abroad. See section 11.

Does an approved I-140 make the employer change automatic? No. An approved I-140 matters to your H-1B time and your green-card planning, but Employer B still needs its own valid H-1B case.

Is the 60-day period still in force? Yes, as of 24 September 2026. DHS has proposed removing it, but that proposal is not law. Because the rulemaking is live, check before relying on it.

The SOSGI bottom line

An H-1B job change is a handoff, not a transfer of Employer A's paperwork.

Employer B must build its own valid case. If you want to start before approval, you must independently qualify for portability. Proper filing matters. The requested start date matters. Your latest I-94 matters. Rejection and denial are different problems. A layoff starts a separate clock. Crossing the cap-exempt line can cost you the whole position. A second pending employer creates a chain. Travel creates a new admission — and, since September 2026, can end a pending change of status outright.

For an Indian professional making a career move, that produces one discipline:

Do not choose your resignation date from the offer letter. Choose it after you understand the immigration timeline.

Know the filing. Know the requested start date. Know your I-94. Know whether you have ever been counted. Know the downside if the petition fails. Then make the handoff.
