F-1 Students in the US: OPT, STEM OPT and the H-1B Bridge (2026)

Over a million international students hold F-1 status, and nearly every one of them is quietly running the same three-stage calculation: how much work the student years allow, how far OPT stretches after graduation, and whether the H-1B lottery — or an O-1 file built in time — lands before the music stops. The rules live in 8 CFR 214.2(f) and USCIS's OPT guidance; here they are in order, with the deadlines that actually end careers when missed.

Stage one: the student years

• The paperwork spine: admission → the school issues the I-20 (SEVP-certified institution) → pay the SEVIS I-901 fee, $350 → DS-160 and the consular interview → F-1 stamp. Maintain full-time enrollment every term; the DSO (designated school official) is the status system's front line — course-load drops, program extensions and every work authorization below run through them;
• On-campus work: up to 20 hours/week while school is in session, full-time during official breaks — no separate USCIS authorization. University labs, libraries, teaching assistantships all count;
• CPT — the curricular route: internships and co-ops that are an integral part of the curriculum (required, or credit-bearing under an established program), authorized by the DSO per employer and dates. The famous trap: 12 months or more of full-time CPT eliminates OPT eligibility entirely — part-time CPT doesn't, and the day-counting discipline belongs to the student, not the DSO;
• What doesn't exist: casual off-campus work, freelancing for U.S. clients, "just Uber" — all status violations that surface years later in green-card files. The F-1's work map is exactly the authorized items and nothing else.

Stage two: OPT — the 12 months everyone plans around

Post-completion OPT grants 12 months of work authorization in a job directly related to the degree. The mechanics that decide outcomes:

• The application window: the I-765 must reach USCIS in the window opening 90 days before program completion and closing 60 days after — and the DSO's OPT recommendation in SEVIS must precede the filing. Every year, students discover the window after it closes; there is no cure;
• Don't work before the EAD arrives: authorization begins on the card's start date, not the job offer's;
• The 90-day unemployment meter: more than 90 days without qualifying employment during initial OPT ends the status. Qualifying employment is generous in form — multiple employers, contract work, unpaid positions and self-employment can count when degree-related and documented — but the SEVP portal reporting duties are real;
• Pre-completion OPT exists (part-time during studies) but consumes the same 12-month pool — almost always the wrong spend.

Stage three: STEM OPT — the 24-month extension

Degrees on DHS's STEM Designated Degree Program List (by CIP code) unlock a 24-month extension, filed before the initial OPT expires, with conditions that shape job choices: the employer must be enrolled in E-Verify, employment must be a bona fide employer-employee relationship (pure gig self-employment doesn't fit), and the pair must maintain a Form I-983 training plan with reporting checkpoints and employer attestations. The unemployment allowance rises to 150 days aggregate across the whole OPT period. A prior eligible STEM degree can support the extension even when the most recent degree isn't STEM — a rule that saves MBA-after-engineering profiles. Total runway: 36 months — three H-1B lottery cycles for most, which is precisely how the system is played.

The bridge: H-1B, cap-gap, and the O-1 alternative

• The lottery math: employers register in March (the H-1B guide carries the 2026 fee and proclamation picture); selection rates in recent cycles have run roughly one-in-three-to-four for a single registration, so 36 STEM months ≈ three-plus draws — the actuarial case for STEM degrees;
• Cap-gap: a timely H-1B petition requesting change of status with an October 1 start automatically extends F-1 status and work authorization from OPT's expiry to the H-1B's start — the statutory bridge over the summer gap;
• Lottery never lands? The realistic exits: the O-1 for profiles that built acclaim during the degree years (publish, judge, win — the criteria are buildable), day-1-CPT programs (a compliance minefield USCIS scrutinizes — treat marketed "day-1 CPT universities" as a red flag, not a strategy), employer transfer to a cap-exempt institution (universities, nonprofit research), the EB-2 NIW filed directly from OPT for strong research profiles, or a Canadian/European plan B — several countries in this journal's coverage court exactly this cohort;
• The 60-day grace period after program or OPT completion allows departure prep, school transfer or change-of-status filing — not work.

The side rules that ambush real lives

• F-2 dependents: spouses may live in the U.S. but cannot work and may study only part-time (children attend school fully) — the constraint that quietly reshapes household finances for married students; the spouse's own F-1 is often the better structure;
• Travel during OPT: re-entry needs the valid F-1 stamp, the EAD card, a job (or job offer) letter and the DSO's recent travel signature on the I-20 — flying home between graduation and the EAD's approval is the classic self-inflicted wound;
• Visa stamp vs status: the stamp can expire while status continues inside the U.S.; it matters only at re-entry — but renewing it abroad during OPT/STEM invites administrative-processing delays that strand workers for weeks;
• Driver's licenses, SSNs, leases all key off SEVIS records being active and accurate — address updates within 10 days are a compliance duty, not a suggestion.
