Is an H-1B Transfer a New Petition? The Legal Answer

Your new employer isn't amending your current H-1B - they're filing an entirely new petition, and that distinction changes your risk and timing.

You got the offer. Better team, better pay, and it's an H-1B employer, so on paper the move should be simple. Then someone tells you it's "just a transfer" and someone else tells you the new employer has to "start your visa over from scratch," and those two things sound like they can't both be true.

They're actually describing the same underlying fact from two angles. Yes, an H-1B transfer is legally a new petition — not an extension, not a modification, not a continuation of your existing H-1B. Your new employer files a brand-new Form I-129 with a new Labor Condition Application, and USCIS adjudicates it as an independent filing. That's also exactly why you're allowed to start working for them well before that petition is approved. The two facts aren't in tension — the second one exists because of the first.

The short legal answer

USCIS has no form, category, or checkbox labeled "H-1B transfer." The word is industry shorthand, not a legal term of art. What actually happens: your prospective employer's immigration counsel prepares a Form I-129 petition, checks "change of employer" on the H Classification Supplement, attaches a newly certified Labor Condition Application (LCA) specific to that employer's worksite and wage level, and files it with USCIS as a standalone petition.

That petition doesn't reference your current employer's approval as its basis. It isn't reviewed for consistency with your old job. It stands or falls on its own record — the new employer's ability to pay the offered wage, the specialty-occupation case for the new role, and the employer-employee relationship being formed. The only thing "portable" about a transfer is your underlying eligibility (you're already an H-1B worker who was counted against the cap) — the petition itself is new.

Why that distinction is worth knowing

Framing the move as a "new petition" rather than a "transfer" changes how you should think about three things: timing, risk, and the cap. Each cuts a different way.

Only the transfer row involves a genuine change of employer, and only that row carries AC21's portability benefit. That's not a coincidence — portability exists specifically to solve the problem a brand-new, independently-adjudicated petition would otherwise create: without it, you'd have to wait months for approval before you could set foot in the new job.

The upside of a new petition: AC21 portability

Because the filing is legally a new petition rather than a modification of your existing status, Congress built a specific bridge for it. Under AC21 §105 (8 USC §1184(n)), you can begin work for the new employer the day USCIS receives the petition — evidenced by the I-797C receipt notice — not the day it's approved. Three conditions have to hold:

1. You were in valid H-1B status, or an authorized period of stay, when the new petition was filed.
2. You were previously counted against the H-1B cap (true for essentially anyone who already holds H-1B status).
3. You have not worked without authorization since your last lawful admission.

The Department of Labor's Fact Sheet 62W is the standard reference for how this interacts with LCA requirements. In practice, the sequence looks like this:

1. New employer's counsel files the LCA with the Department of Labor for the new worksite and wage level.
2. LCA is certified, then attached to a fresh Form I-129 with the change-of-employer box checked.
3. The new employer files the I-129 with USCIS — this is the "new petition," filed independently of your current employer's records.
4. USCIS issues a receipt notice. This is the portability trigger — you may start working for the new employer once it's issued, not once the case is decided.
5. USCIS adjudicates the petition on its own merits — approval, denial, or a Request for Evidence.
6. You (and your attorney) decide when to resign from your current employer — on the receipt notice, or after approval, depending on how much risk you're willing to carry during the gap.

Because the petition is independent, this also means you can legally hold two H-1B petitions active at once — one with your current employer, one with the new one — for as long as it takes the new filing to be decided. That's the same legal mechanism behind concurrent H-1B employment, where a worker holds a primary H-1B and a second, part-time H-1B with a different employer simultaneously. Both arrangements exist only because separate petitions don't need to reconcile with each other.

The trade-off: independent adjudication means independent risk

The same fact that lets you start early also means the new petition isn't guaranteed just because your last one was approved. USCIS's H-1B modernization rule, effective January 2025, directs officers to defer to a prior petition's approved determinations when the underlying facts haven't changed — but the facts here have changed: new employer, new worksite, new wage level, sometimes a new job title. That limits how far deference actually reaches. A new company with a thin financial history, a wage level that doesn't match the role, or a generic job description can draw a Request for Evidence or a denial even though your prior H-1B was clean.

If the new petition is denied after you've already started working there and left your old job, you can fall out of status. Whether you have a way back depends on facts specific to your case — whether your old employer has formally withdrawn its petition, whether a grace period applies, and how much time is left to attempt another filing. This is exactly the kind of fork where a licensed immigration attorney, not general guidance, needs to look at your paperwork before you move. If your current employer is the one considering pulling their petition, our guide on withdrawing and refiling an H-1B petition covers what that does to your status.

Does "new petition" mean you're back in the lottery?

Almost always, no. AC21 makes clear that a worker who was already counted against the H-1B cap doesn't get counted again just because a new employer is filing. That's true even if the new employer is cap-subject and you've never worked there before — your cap-exemption travels with you, not with the employer.

The one real exception: if you currently work for a cap-exempt employer — a university, an affiliated nonprofit, or a government research organization — and you move to a cap-subject employer, that move does require entering the lottery, because you were never actually run through the cap-subject numbers in the first place. If that lottery entry becomes necessary, it now runs under the wage-weighted selection system that took effect February 27, 2026, where the offered role's OEWS wage level determines how many entries you get — Level IV roles receive more entries than Level I roles. That makes the wage level attached to the new offer a detail worth raising with the new employer before the LCA is filed, not after.

Does a "new" petition mean the $100,000 fee applies?

This question comes up because "new petition" sounds like it could trigger fees aimed at new H-1B filings. As of this writing, it's moot either way: the $100,000 supplemental H-1B fee created by the September 2025 proclamation was vacated by a federal district court on June 8, 2026, and the First Circuit declined to reinstate it on July 24, 2026. As of August 2026, the fee is not being collected, though the government's appeal is still pending and the underlying proclamation's 12-month restriction is set to sunset on September 20, 2026 unless extended. Treat this as an unsettled area — if you're weighing a transfer and cost is part of your calculus, confirm the current status with your employer's immigration counsel rather than relying on anything published before those rulings.

If your transfer involves travel

A transfer petition doesn't by itself require a new visa stamp — if you stay in the US, a change of employer is typically processed domestically and your existing stamp remains usable for reentry as long as it's valid for the classification. But if you travel internationally after the transfer and need a fresh H-1B visa stamp reflecting the new employer, know that the interview waiver ("dropbox") option for H-1B applicants ended on October 1, 2025. Every H-1B stamping appointment now requires an in-person consular interview, generally in your country of nationality or usual residence — plan the appointment timeline accordingly.

Common mistakes

• Assuming "transfer" means continuity. Nothing carries over automatically except your cap-exempt status, your I-140 priority date if you have one, and time already used toward the six-year maximum. The approved I-140 itself doesn't transfer — a new employer sponsoring your green card typically starts a fresh PERM and I-140, though you keep your priority date. Our guide to AC21 portability and changing jobs during the green card process covers what specifically survives a job change at each stage.
• Resigning before the new petition is even filed. If there's no I-129 receipt notice yet, there's no portability protection — you'd be resigning into a gap with no legal basis to work anywhere.
• Treating a prior approval as a guarantee. Deference to past determinations has limits when the employer, worksite, or wage level changes; a weak new petition can be denied even with a clean H-1B history.
• Confusing an amendment with a transfer. If you're staying with the same employer but changing worksite or duties, that's an amendment question governed by Matter of Simeio Solutions, not a transfer, and AC21 portability doesn't apply the same way.
• Not checking the wage level before the new LCA is filed, especially if a lottery entry might be needed. Once the LCA is certified, the wage level is locked in for that petition.

What this means in practice

Legally, an H-1B transfer is nothing more than a new, independent I-129 petition filed on your behalf by a new employer. That single fact explains the good news (you can start working the day USCIS receives it, thanks to AC21 portability, without waiting weeks or months for an approval) and the real risk (it's judged on its own merits, so a clean prior H-1B history doesn't insulate a new petition built on a weak case). For the practical step-by-step timeline of filing one, our H-1B transfer playbook walks through the weeks between offer and start date. Here, the legal mechanics are the whole answer — it's a new petition, and every downstream rule about timing, the cap, and portability follows from that one fact.

Frequently asked questions

Is an H-1B transfer legally a new petition? Yes. There is no USCIS filing category called an H-1B transfer — what people call a transfer is a fresh Form I-129 petition that your new employer files, checking the change-of-employer box on the H Classification Supplement. It is adjudicated independently from your current H-1B, not treated as a continuation or amendment of it.

Do I have to enter the H-1B lottery again to transfer employers? No, in almost all cases. Because you were already counted against the H-1B cap on a prior petition, AC21 makes a same-status move cap-exempt regardless of whether the new employer is cap-subject. The common exception is moving from a cap-exempt employer, such as a university or nonprofit research organization, to a cap-subject employer — that move can require winning a new lottery slot.

Can I start working for my new employer before the transfer petition is approved? Often yes. Under AC21 Section 105 portability, codified at 8 USC 1184(n), you may begin work for the new employer once USCIS receives a non-frivolous I-129 petition with a certified Labor Condition Application, evidenced by the receipt notice, not the approval. This requires that you were in valid H-1B status when the new petition was filed, were previously counted against the cap, and have not worked without authorization since your last lawful admission.

Does an H-1B transfer reset my six-year H-1B time limit? No. Because the new filing is a separate petition rather than a new grant of status, the time you have already used toward the six-year H-1B maximum carries forward unchanged. A transfer changes your employer, not your clock.

What is the difference between an H-1B transfer, an amendment, and an extension? A transfer is used when you move to a different employer and requires a brand-new I-129 petition with a new Labor Condition Application. An amendment is used when the same employer materially changes your worksite or job duties, following the standard set in Matter of Simeio Solutions. An extension is used when the same employer wants more time in the same role under your existing terms. Only the transfer scenario carries AC21's portability right to start work on the receipt notice, because only that scenario involves a change of employer.
