📋 Summary:
H-1B portability allows you to start working for a new employer once they file an H-1B petition, even before approval. You don't need to wait for the new petition to be approved if your previous H-1B was valid.
H-1B portability (AC21 Act) allows you to change employers more easily:
- Start working immediately: Once new employer files H-1B petition, you can start working
- No need to wait: Don't need to wait for approval if previous H-1B was valid
- Previous H-1B must be valid: Your current H-1B must not have expired
- New petition must be filed: New employer must have filed I-129 before you start
Additional Information:
- Portability applies to H-1B extensions and transfers
- You can work for new employer while petition is pending
- If petition is denied, you must stop working immediately
- Premium processing recommended for faster approval
- Keep pay stubs and employment records
💡 In Other Words:
H-1B portability is like being able to switch jobs without waiting for approval. It's like getting a "transfer pass" - once your new employer files the paperwork, you can start working there immediately, even before the government officially approves it. But if the approval gets denied later, you'll have to stop working.
