Can I change employers between STEM OPT and my H-1B start date?

TL;DR: Yes, but carefully. Your approved H-1B belongs to the petitioning employer - it does not transfer automatically. A new employer must file its own H-1B petition (cap-exempt "change of employer," since you were already counted in the lottery). If your STEM OPT is valid, update your I-983 and report the change within 10 days; if you're relying on cap-gap, switching is far riskier because cap-gap ties to the approved petition.

The scenario (asked constantly on r/f1visa)

Typical case, verbatim pattern from r/f1visa: "My STEM OPT expires Aug 27. My H-1B is approved with an Oct 1 start. Can I switch to a new employer before Oct 1?" Two separate questions hide inside it:

1. Work authorization until Oct 1. STEM OPT expiring Aug 27 with an approved change-of-status H-1B puts you in the cap-gap extension: your F-1 status and work authorization extend automatically from OPT expiry to September 30, because of that specific approved petition. Cap-gap is petition-dependent. If the original employer withdraws the petition when you quit, your cap-gap collapses - you'd stop working immediately and enter your 60-day grace period.

2. The H-1B itself. H-1Bs are employer-specific. The new employer must file a new I-129 petition. Good news: once you've been counted against the cap, the new petition is cap-exempt - no new lottery. With premium processing ($2,805), decisions arrive in 15 business days. Before Oct 1 you do not yet hold H-1B status, so you must wait for approval and an Oct 1 (or later) start.

Safe vs. risky paths

Step-by-step for a clean switch

1. Decide timing: before OPT expiry, or after Oct 1. Avoid moves during cap-gap.
2. If moving on STEM OPT: new employer must be E-Verified; sign a new I-983 training plan; report to your DSO within 10 days.
3. New employer files a cap-exempt H-1B petition (change of employer/status) with premium processing.
4. Do not let the old employer withdraw before your new approval if you depend on cap-gap.
5. After Oct 1 with H-1B active, AC21 portability lets you start at any new employer upon USCIS receipt of its petition.

FAQ

Does my approved H-1B move with me? No. It belongs to the petitioner. The new employer files its own petition - cap-exempt since you were already selected and counted.

Do I go through the lottery again? No, as long as you were counted against the cap in the last 6 years.

What happens to cap-gap if I quit in September? If the sponsoring employer withdraws the petition, cap-gap ends and so does your work authorization.

Can the new petition keep the Oct 1 start date? Yes - a change-of-status petition can request an Oct 1 start; premium processing makes the timeline workable.

What if the original petition is withdrawn after Oct 1? Once your H-1B status is activated, a withdrawal doesn't undo it; you have a 60-day grace period between jobs.
