What is an H-1B transfer, and is it really a 'transfer'?
"H-1B transfer" is everyday shorthand, not a legal term. What actually happens is that a new employer files a fresh I-129 petition to employ you in H-1B status — there is no dedicated transfer form. The good news that surprises many workers: because you already hold H-1B status, you are exempt from the annual cap, so a transfer does not go through the H-1B lottery again. The mechanics of the underlying petition are the same ones covered in our H-1B visa process guide; the difference is that this filing rides on your existing status rather than a cap selection.
There is also no limit on how many times you can change employers on H-1B, and each move resets nothing about your six-year clock. This portability is one of the H-1B's most valuable features, and it is what lets skilled workers actually move between US employers — a flexibility that stands in contrast to more employer-locked routes discussed in our L-1 vs H-1B comparison.
When can I start working for the new employer?
Under AC21 portability, you may begin working for the new employer as soon as USCIS receives the new I-129 petition — proven by the I-797C receipt notice — not when it is approved. You do not have to wait three-to-six months for a decision. In practice, experienced employers file the petition and wait for the dated receipt notice before putting you on payroll, and you should keep a copy of that receipt as your proof of authorized employment during the pending period. The US Department of Labor's H-1B portability fact sheet is the authoritative source on how this works.
For portability to apply, three conditions must hold: you were lawfully admitted, the new employer files a non-frivolous petition before your current authorized stay expires, and you have not worked without authorization. Miss the timing — for example, letting your status lapse before the new petition is filed — and you lose the portability protection. This is exactly the kind of sequencing where our guide on when you need an immigration lawyer is worth reading before you resign from your current job.
What is the step-by-step transfer process?
The sequence is: (1) the new employer obtains a certified Labor Condition Application (LCA) from the Department of Labor — typically about 7 business days through the DOL FLAG system; (2) the employer files the I-129 with supporting documents and fees; (3) USCIS issues the I-797C receipt, at which point portability lets you start; and (4) USCIS approves the petition, or issues an RFE first. If you want that final approval fast, the employer can add premium processing for a 15-business-day decision. Gather your own documents early — degrees, pay stubs, and prior approval notices — the same evidence themes as the original H-1B petition.
On fees: the base I-129 fee is $780, and the employer is generally responsible for the required H-1B costs — a worker reimbursing the employer's mandatory fees can create compliance problems, a point we stress in our H-1B visa cost breakdown. Premium processing, if used, adds the $2,965 I-907 fee. Note that a transfer does not restart your green-card process — an approved I-140 and priority date can be preserved and carried to the new employer, which is often the single most important thing to protect when you switch jobs.
What are the risks of transferring, and how do I reduce them?
The main risk is timing. If you quit before the new petition is filed and received, you can fall out of status and lose portability. A denied transfer petition after you have already started work is another exposure — you would generally have to stop working and may need to leave the US or find another employer to file quickly. Mitigate both by not resigning until the new I-129 receipt is in hand, and by considering premium processing when the stakes or the start date are tight, as our premium processing guide explains.
The other commonly overlooked risk is your green-card progress. If your current employer sponsored you and you have an approved I-140, understand what carries over before you move — our H-1B to green card guide covers priority-date retention, and for the labor-certification stage that underpins it, see PERM labor certification explained. Handled correctly, a job change can be seamless; handled carelessly, it can cost you years of green-card progress. Browse the Visa Answers hub for the full work-visa roadmap.

Related Questions
Can I start working before my H-1B transfer is approved?
Yes. Under AC21 portability, you can begin work for the new employer as soon as USCIS receives the new I-129 petition, shown by the I-797C receipt notice. You do not have to wait for approval, but you must not have fallen out of status before the petition was filed.
Does an H-1B transfer go through the lottery again?
No. Because you already hold H-1B status, you are exempt from the annual cap, so a transfer to a new employer skips the lottery entirely. There is also no limit on how many times you can transfer, and it does not restart your six-year H-1B clock.
How long does an H-1B transfer take in 2026?
Standard processing runs roughly 3 to 6 months, but you can start work much sooner on the receipt notice. If the employer files Form I-907 premium processing for $2,965, USCIS commits to a decision within 15 business days.
What happens to my green card process if I transfer?
A transfer does not automatically restart it. If you have an approved I-140, you can generally retain your priority date and carry it to the new employer's green-card process. Protecting that date is often the most important consideration when changing jobs on H-1B.
Who pays for an H-1B transfer?
The new employer is generally responsible for the required H-1B petition costs, including the base I-129 fee. Having the worker reimburse the employer's mandatory fees can create Department of Labor compliance problems, so most costs properly sit with the employer.
