F-1

Student Visa — OPT,
STEM OPT & H-1B

The F-1 student visa is the primary academic visa for full-time students at US universities and colleges. Beyond the degree itself, F-1 unlocks Optional Practical Training (12 months) and a STEM OPT extension (24 months additional), providing up to 3 years of post-graduation work authorization — and a critical bridge to H-1B sponsorship for the most competitive international students.

What is the F-1 visa?

The F-1 nonimmigrant visa is issued to full-time academic students at US universities, colleges, language schools, and other SEVP-approved institutions. Students must maintain full-time enrollment, demonstrate sufficient financial support, and maintain a residence abroad they do not intend to abandon — though F-1 technically does not carry dual intent, USCIS permits green card applications while in F-1 status. The F-1 is managed through SEVIS (Student and Exchange Visitor Information System) and the student's Designated School Official (DSO), not USCIS directly. After graduation, F-1 unlocks the Optional Practical Training (OPT) and STEM OPT extension programs, which are among the most commonly litigated and compliance-intensive parts of F-1 practice for immigration attorneys. F-1 is also the entry point for H-1B sponsorship, and cap-gap rules protect students whose OPT expires before their H-1B start date. See the official ICE SEVIS F-1 guidance.

OPT — 12 Months Post-Graduation
Post-completion OPT provides 12 months of work authorization related to the student's major field of study. Students must apply through their DSO and then file Form I-765 with USCIS — applications must be submitted no later than 60 days after the program end date and no earlier than 90 days before. OPT must be used within 14 months of the program end date. Unemployment of more than 90 days during OPT violates F-1 status.
🔬
STEM OPT — 24 Additional Months
F-1 students with degrees in STEM fields (as defined by the DHS STEM Designated Degree Program list) may apply for a 24-month extension on Form I-765 — bringing total OPT to 36 months. The employer must be enrolled in E-Verify. A formal training plan (Form I-983) is required and must be updated when the training plan or employer information changes materially. This extension is the primary competitive advantage for STEM graduates navigating the H-1B lottery.
🔄
H-1B Cap-Gap Protection
F-1 students on OPT whose H-1B petition is filed by April 1 for an October 1 start date benefit from automatic cap-gap extension of their F-1 status (and OPT work authorization) through September 30. This bridges the gap between OPT expiration and H-1B start date. The protection terminates if the H-1B petition is denied, withdrawn, or revoked — making timely H-1B filing and premium processing critical for students with expiring OPT.

How the F-1 to H-1B path works

01
School admission and I-20 issuance
The student receives an acceptance letter from a SEVP-approved school. The DSO creates a SEVIS record and issues Form I-20 (Certificate of Eligibility for Nonimmigrant Student Status). The student pays the SEVIS fee ($350), completes Form DS-160, and attends a consular interview. F-1 visa stamps may be obtained up to 120 days before the program start date but the student cannot enter the US more than 30 days before.
02
Maintain full-time enrollment and F-1 status
The student must remain enrolled full-time (usually 12 credit hours per semester for undergraduates), report any address change to the DSO within 10 days, and work only within authorized scope (on-campus employment or DSO-authorized CPT/OPT). Any change of major, school transfer, or reduced course load requires DSO approval and updated SEVIS record. Unlawful presence accumulates immediately upon status violation.
03
Apply for OPT before graduation
The student requests OPT from their DSO, who updates SEVIS and issues a new I-20 recommending OPT. The student then files Form I-765 with USCIS. Applications open 90 days before the program end date. Given USCIS processing times (typically 3–5 months), students should apply as early as possible. The EAD card shows the authorized OPT start and end dates and must be received before beginning employment.
04
STEM OPT extension (if eligible)
STEM students file a new I-765 before OPT expires. The employer must be enrolled in E-Verify and co-sign Form I-983 (Training Plan for STEM OPT students). STEM OPT employers must report material changes (new training plan, reduced hours below 20/week, layoff) to the DSO within 5 business days. USCIS may conduct site visits. Filing early — at least 90 days before OPT expiration — is critical; automatic 180-day cap-gap extension applies to timely STEM OPT filers while the application is pending.
05
H-1B registration and cap-gap
Students on OPT who are selected in the H-1B lottery have their employer file Form I-129 for an October 1 start date. If OPT expires before October 1, cap-gap automatically extends authorized status through September 30 provided the I-129 was filed timely (by April 1) and remains pending, approved, or under appeal. Premium processing is strongly recommended for students with expiring OPT to obtain early certainty.

F-1 FAQ

What is OPT and how long does it last?

Optional Practical Training (OPT) provides 12 months of work authorization related to the student's degree field, used after graduation. Students apply through their DSO and file Form I-765 with USCIS. The application window opens 90 days before graduation and closes 60 days after. Pre-completion OPT reduces the available post-completion period. Students may not be unemployed for more than 90 cumulative days during OPT without violating their F-1 status. See USCIS OPT guidance.

What is the STEM OPT extension?

STEM OPT grants an additional 24 months of work authorization to F-1 graduates with STEM degrees who are employed by E-Verify employers. Total post-graduation work authorization reaches 36 months. The employer must provide a formal training plan (Form I-983) and report material changes to the DSO within 5 business days. Unemployment limits are stricter — no more than 150 cumulative days across all OPT periods (pre-completion, post-completion, and STEM extension). Application must be filed before the initial OPT expires.

What is CPT (Curricular Practical Training)?

CPT authorizes F-1 students to work in positions that are an integral part of their curriculum — typically required internships or co-op programs. CPT is authorized by the DSO at the school (not USCIS) and must be approved before the student begins working. Part-time CPT (20 hours or less per week) does not reduce OPT eligibility. Full-time CPT (more than 20 hours per week) for 12 cumulative months eliminates OPT eligibility entirely, which can significantly affect the student's post-graduation immigration options.

What is H-1B cap-gap and how does it protect F-1 students?

Cap-gap is a regulatory protection that extends an F-1 student's status (and OPT work authorization) automatically from the OPT expiration date through September 30 when a timely H-1B petition (filed by April 1) is pending or approved. Without cap-gap, students whose OPT expires before October 1 would be out of status before their H-1B begins. Cap-gap terminates immediately upon denial, withdrawal, or revocation of the H-1B petition — students in this situation must stop working and may need to depart the US.
