H-1B Transfer Basics: What Happens When You Switch Employers

An H-1B transfer isn't really a transfer, it's a brand-new petition, and that one fact changes almost everything about the timeline.

You have an offer from a new company and you're currently on H-1B. The question hits immediately: what actually happens to your visa when you switch employers? Does it move with you? Do you start over? Does the offer fall apart if paperwork stalls?

Here's the direct answer. A transfer of your H-1B visa isn't a transfer in the literal sense — nothing physically moves from one employer to another. Your new employer files a brand-new H-1B petition on your behalf, and a federal portability rule lets you begin working for them the moment USCIS receives that filing, not the day it's approved. Everything else — your priority date, the years you've already used, whether you need to re-enter the lottery — depends on what you're carrying with you and where you are in your immigration timeline.

What "H-1B transfer" actually means

H-1B status is employer-specific. There is no USCIS form called a "transfer," and no single record that gets reassigned from one company to another. What people call an H-1B visa transfer is really a new employer filing a new Form I-129 petition, backed by its own Labor Condition Application (LCA) certified with the Department of Labor, describing a job, a wage, and a worksite that belong to them alone.

That distinction matters because it means the new petition stands or falls on its own facts. A strong H-1B history with your current employer doesn't automatically carry weight with the new one's filing — USCIS evaluates the new role, the new LCA, and the new employer-employee relationship independently.

The rule that lets you start before approval

The reason H-1B transfers don't force a gap in employment is AC21 §105 (codified at 8 USC §1184(n)), often called H-1B portability. It lets you begin work for a new employer the moment USCIS receives a non-frivolous I-129 petition with a certified LCA, rather than waiting for approval, provided three things are true:

1. You are in valid H-1B status, or another authorized period of stay, when the new petition is 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.

If all three hold, the receipt notice — Form I-797C — is your green light to start, not the eventual approval notice. For the fuller mechanics of this rule, including how it interacts with premium processing and denial risk, see our H-1B transfer playbook.

What happens, step by step, when you switch employers

1. You accept a written offer but don't resign yet. Everything downstream depends on paperwork that hasn't been filed.
2. The new employer's counsel files an LCA with the Department of Labor for the new role, certifying the wage level and worksite.
3. The new employer files Form I-129 with the certified LCA attached to USCIS. This filing is the actual "transfer" — there's no separate transfer form.
4. USCIS issues a receipt notice (I-797C). If the AC21 §105 conditions above are met, this is the date you can start working for the new employer.
5. The petition sits in USCIS's queue for adjudication, unless the employer opted into premium processing, which forces USCIS to take action — approval, denial, or a Request for Evidence — within 15 business days of accepting the upgrade. Standard-queue processing times vary by service center and change throughout the year; check USCIS's official processing-times tool with your own receipt number rather than relying on a number from any article, including this one.
6. USCIS approves, denies, or issues an RFE. On approval, you get a new I-797 tied to the new employer, and it becomes the petition that governs your work authorization going forward.
7. Your existing visa stamp still works for entering the US as long as it's unexpired and matches your status — but it doesn't automatically cover the new employer. You'll need a new stamp only when you next travel internationally and try to re-enter.

If your move is to a different office of the same multinational company rather than a genuinely new employer, an intracompany transfer may be worth comparing against a fresh H-1B filing — see our breakdown of H-1B vs. L-1 for how the two paths differ on timing and flexibility.

What carries over, and what doesn't

If you're already mid-green-card process, a different rule applies

Everything above describes moving between employers while you're simply on H-1B status. If you're further along — specifically, if you have a Form I-485 adjustment of status application that's been pending for 180 days or more, in the same or a similar occupational classification — a separate AC21 provision (INA §204(j) job portability) lets you change employers without restarting the green card process from scratch. That's a materially different analysis from the H-1B portability described here, and it's worth understanding on its own terms before you decide whether a move is worth it at your stage. Our guide to AC21 portability and green-card job changes walks through it in depth, and our comparison of switching employers vs. staying for your green card is the right next read if you're weighing the decision itself rather than just the mechanics.

Does the $100,000 H-1B fee affect your transfer

As of August 2026, no — because the fee isn't being collected from anyone right now. A federal district court in Massachusetts vacated the underlying proclamation on June 8, 2026, finding it exceeded executive authority and violated the Administrative Procedure Act. The government asked the First Circuit to reinstate the fee while it appealed; the court declined on July 24, 2026. The appeal is still pending and the proclamation's underlying 12-month restriction is set to sunset on September 20, 2026 unless extended, so this is a live legal situation rather than a settled one. Don't assume today's status will hold through your filing window — confirm it with your employer's immigration counsel before you make a decision that depends on it.

If you need to travel after you switch employers

Switching employers doesn't require a new visa stamp if you stay inside the US, but many candidates end up traveling during or shortly after a transfer anyway. Two things changed recently that make this riskier than it used to be. First, the Department of State ended the H-1B interview waiver — commonly called dropbox — on October 1, 2025, so every H-1B stamping appointment now requires an in-person consular interview, including routine renewals with the same employer. Second, applicants generally must apply in their country of nationality or usual residence, since third-country stamping is no longer a reliable option. If your transfer is still pending or freshly approved and you're weighing a trip abroad, read our guide on the $100,000 fee and traveling while a petition is pending before you book anything, and build in real buffer time for an interview slot.

When switching employers means entering the lottery again

Most H-1B-to-H-1B transfers skip the lottery entirely, because you were already counted against the cap the first time you were selected. The one common exception: moving from a cap-exempt employer — a university, an affiliated nonprofit, or a nonprofit or governmental research organization — to a cap-subject employer. That move does require entering the lottery as if you were a new registrant.

If that applies to you, know that the lottery itself changed. Since February 27, 2026, H-1B cap selection has used a wage-weighted system rather than a flat random draw: a registration tied to an OEWS Level IV wage gets four entries in the pool, Level III gets three, Level II gets two, and Level I gets one. That makes the wage level on your future LCA a genuinely negotiable input to your odds, not just a paperwork detail — it's worth raising with the new employer before the LCA is filed, not after.

Common mistakes

• Resigning before the new I-129 is filed. If anything delays the filing, you're left with no valid H-1B employer to fall back on.
• Assuming your priority date and years used reset with a new employer. They don't — the 6-year clock and any retained priority date both carry forward.
• Assuming an old visa stamp covers the new employer indefinitely. It gets you back into the country on your current status, but you'll need a new stamp tied to the new employer for future re-entry in most cases.
• Treating the LCA as a formality because "it's just a transfer." It's an independent, DOL-audited filing describing a specific wage and worksite; errors here can trigger scrutiny on the whole petition.
• Not budgeting extra time for consular stamping. With the interview waiver gone, a trip abroad now means booking and sitting for an in-person interview, not dropping documents at a window.
• Deciding to switch without weighing where you are in the green-card process. The mechanics of the H-1B transfer are usually the easy part; the harder question is often whether the move makes sense given a pending I-140 or I-485.

Frequently asked questions

Is an H-1B transfer a new petition or does my current visa move with me? It's a new petition. Your new employer files a fresh Form I-129 and a newly certified Labor Condition Application with your name on it, and nothing about your existing H-1B physically moves. Because AC21 portability governs the timing, you can typically begin the new job as soon as USCIS issues a receipt notice for that filing, not when it's approved.

Can I start working for the new employer before the transfer is approved? Yes, under AC21 Section 105 portability, as long as you are in valid H-1B status when the new petition is filed, were previously counted against the cap, and have not worked without authorization. The trigger is USCIS receipt of the petition, not the approval, so many candidates start on the strength of the receipt notice alone. Waiting for approval before you resign your current job is still the lower-risk path if your timeline allows it.

Does the $100,000 H-1B fee apply when I switch employers? As of August 2026, the $100,000 fee is not being collected at all. A federal court vacated the underlying proclamation on June 8, 2026, and the First Circuit denied the government's request to reinstate it on July 24, 2026, so the fee is currently blocked regardless of whether a filing is a transfer or a new hire. The appeal is still pending, so this could change, and confirm the current status before you rely on it.

Do I keep my place in line for a green card if I change employers? It depends on your stage. If a prior employer's I-140 was approved, you generally keep that priority date even though the new employer will typically need to file its own PERM and I-140 to sponsor you going forward. If you already have an I-485 pending for 180 days or more in the same or a similar occupation, a separate AC21 portability rule lets you change jobs without restarting the green card process.

What happens if I need to travel internationally after I switch employers? You will likely need a new H-1B visa stamp for the new employer before re-entering the US, and as of October 1, 2025 the interview waiver, sometimes called dropbox renewal, was eliminated for H-1B applicants. Plan on an in-person consular interview, generally in your country of nationality or usual residence, and build extra time into your travel plans.
