OPT to H-1B: A Step-by-Step Guide

Moving from student work authorization to an H-1B is one of the most common — and most date-sensitive — transitions. Here is how it works and how the cap-gap protects you.

Key takeaways
  • The move depends on the H-1B lottery and careful date alignment.
  • The cap-gap can extend your OPT so you keep working until the H-1B starts.
  • Missing a date can create a status or work gap — plan early.

If you are working on OPT after graduation, the H-1B is usually the next step. The transition is doable, but it runs on dates that have to line up. Here is the path and the protections that keep you working along the way.

The Path

  1. Find an employer willing to sponsor your H-1B.
  2. Get registered for the H-1B lottery during the registration window.
  3. If selected, your employer files the full petition.
  4. If approved, your H-1B status typically begins later that year.

The Cap-Gap: Your Safety Bridge

Your OPT may end before the H-1B start date. The cap-gap extension can bridge that gap — automatically extending your OPT work authorization until the H-1B begins — but only if:

  • You were selected and a timely H-1B petition was filed on your behalf
  • The petition requests a start date for the upcoming cap year
  • You maintain your status throughout

It is a bridge, not a guarantee — it only holds when the dates and filings were handled correctly.

"OPT to H-1B is really four dates that must connect: your OPT end, the filing, the selection, and your H-1B start. The cap-gap links them — if nothing slips."

Watch These Dates

  • Your exact OPT (and any STEM OPT) end date
  • The registration and petition windows
  • Your H-1B requested start date
  • Any international travel during the cap-gap period — it can break the bridge

If You Are Not Selected

If you are not picked, your OPT continues only for its normal validity. Talk to your employer and an attorney early about a STEM extension (if eligible), another registration next year, or a different visa path so you do not run out of authorized time.
