H-1B Transfer Without Your Employer Knowing: What the Law Actually Says
One of the most common questions from H-1B workers: can you start the transfer process without your current employer finding out? The short answer is yes — and it is entirely legal. H-1B portability, established under AC21, was specifically designed to protect workers from employer retaliation during a job change. This guide covers exactly how the process works, what your employer can and cannot see, and how to protect your status throughout the transition.
Frequently asked questions
Will my current employer be notified when I start an H-1B transfer?
No. USCIS does not notify your current employer when a transfer petition is filed. Your employer has no way to find out unless you tell them or they run an E-Verify check after you have already started at the new job.
When can I start working for my new employer during an H-1B transfer?
You can start working at the new employer as soon as you receive the I-797C receipt notice for the transfer petition. You do not need to wait for approval — the receipt notice alone gives you portability rights under AC21.
What documents does my new employer need to file the H-1B transfer?
Your new employer needs your current H-1B approval notice (I-797B), your passport copy, your most recent I-94 printout, and recent pay stubs from your current employer. Your current employer does not need to provide anything or sign anything.
