F-1 OPT to H1B: The Complete Step-by-Step Transition Guide (2026)
From OPT application to H1B approval — every step, timeline, and requirement explained. Including STEM OPT extension, cap-subject vs cap-exempt, and what to do if you miss the lottery.
⚡ Key timeline:
F-1 → Post-completion OPT (12 months) → STEM OPT Extension (24 months) → H1B (3 years, renewable). Total pathway: up to 6 years from graduation to H1B, with 3 chances at the lottery if you play it strategically.
The Complete OPT → H1B Roadmap
While on F-1 (before OPT)
- Maintain full-time enrollment and SEvisa status
- Apply for OPT 90 days before graduation (but no earlier)
- Target graduation dates that align with October 1 H1B start
Post-completion OPT (12 months)
- File for OPT through your DSO — allows 12 months of work
- Begin job search targeting H1B sponsors immediately
- Track your 90-day unemployment limit carefully
- If STEM degree: file STEM OPT extension before OPT expires
STEM OPT Extension (+24 months)
- File I-983 Training Plan with your employer
- Report to DSO every 6 months
- Total OPT = 36 months — gives you 3 shots at H1B lottery
H1B Registration (March)
- Employer submits your basic info + $215 fee to USCIS
- Registration window: March 1–18 (exact dates vary)
- US master's degree? You enter both regular + master's cap pools (better odds)
H1B Selection & Filing
- Late March: USCIS notifies selected registrants
- April–June: Full petition assembled and filed
- Include LCA, support letter, credentials, and transcripts
H1B Approval → Oct 1 Start
- Standard processing: 3–5 months
- Premium processing ($2,805): 15 business days
- October 1: H1B starts — you're now an H1B worker
STEM OPT: The Strategic Advantage
If your degree is in STEM (Science, Technology, Engineering, or Mathematics), the 24-month STEM OPT extension is your most important tool. It gives you 36 total months of OPT work authorization — meaning 3 shots at the H1B lottery instead of 1.
To qualify: your degree must be from a STEM-designated program (check the DHS STEM Designated Degree Program List), and your employer must be enrolled in E-Verify. File the STEM extension at least 90 days before your OPT expires.
Track your 90-day unemployment limit carefully during OPT. Exceeding it violates your F-1 status. Use JobOS Tracker to log your employment dates.
If You Don't Get Selected in the Lottery
Lottery selection is ~28%. Here's what to do if you're not selected:
STEM OPT Extension
Stay on OPT another 24 months, re-enter lottery next year
Cap-Exempt Employer
Work at a university or nonprofit — they file H1B anytime, no lottery
O-1A Visa
For extraordinary ability — high bar, but no cap or lottery
EB-2 NIW Self-Petition
Self-petition for green card if your work is of national interest

Finding an H1B Sponsor
Not every company that posts jobs will sponsor H1B. The most reliable signal is their history — companies that have filed H1B petitions before are far more likely to do it again. Use JobOS's H1B company database (built from USCIS LCA records) to identify sponsors before applying.
