Everything you need to know about transitioning from OPT to H-1B visa status. Timeline, documentation, and important considerations.

Understanding the OPT to H-1B Transition

Transitioning from OPT to H-1B can be complex. This guide explains the process step by step, helping you navigate this critical phase of your career in the U.S.

What is OPT?

Optional Practical Training (OPT) allows F-1 students to work in the U.S. for up to 12 months (or 36 months for STEM fields) after graduation.

Timeline Considerations

Timing is crucial when transitioning from OPT to H-1B:

  • Cap-Gap Extension: If your H-1B is approved while on OPT, your status extends until October 1st
  • Filing Window: H-1B petitions are typically filed in April
  • Start Date: H-1B status begins on October 1st

Documentation Requirements

Make sure you have all necessary documentation:

  • Valid I-20 with OPT authorization
  • Employment verification letters
  • Pay stubs and tax documents
  • Degree certificates and transcripts
  • Passport and visa documents

Common Scenarios

Scenario 1: OPT Expires Before H-1B Starts

If your OPT expires before October 1st and your H-1B is approved, you may need to leave the U.S. and return with H-1B visa stamp.

Scenario 2: Cap-Gap Extension

If your OPT is valid through October 1st and H-1B is approved, you get automatic cap-gap extension.

Important Tips

  • Start the H-1B process early
  • Maintain valid F-1 status throughout
  • Keep all documents organized
  • Work closely with your employer and attorney
  • Plan for potential travel restrictions
