F-1 student work authorization limits in the US with an EAD

Work authorization types for F-1 students

F-1 students work in the US through five distinct pathways. On-campus employment is available immediately with DSO approval. Optional Practical Training (OPT) authorizes off-campus work in your field before or after graduation. Curricular Practical Training (CPT) covers internships as part of your degree requirements. Economic hardship work authorization permits off-campus work for unforeseen financial emergencies. International organization employment is available with sponsorship from a State Department-designated entity.

On-campus work limits

During the academic term, F-1 students are limited to 20 hours per week on campus. This cap applies regardless of the employer, including your school, on-campus contractors, or work-study programs. The 20-hour limit is a hard ceiling under federal regulations. Working beyond 20 hours during the academic term is a violation of F-1 status under 8 CFR 214.2(f)(9) and risks SEVIS record termination by the DSO or SEVP, although termination decisions sit with the DSO and SEVP rather than triggering automatically for a minor overage.

During official school breaks, including winter, spring, and summer holidays, you are permitted to work more than 20 hours per week on campus. "Full-time" under SEVP guidance is generally any schedule above 20 hours per week, so any hours above the 20-hour academic-term cap are permissible during officially designated breaks. You do not need an EAD for on-campus work, only DSO approval documented in SEVIS.

Optional Practical Training (OPT): 12-month base duration

OPT provides 12 months of work authorization either before graduation (pre-completion OPT, part-time during school) or after graduation (post-completion OPT, full-time). Per USCIS Policy Manual Vol. 2, Part F, Ch. 5 , the student must have been lawfully enrolled on a full-time basis for one full academic year (as defined by the school, typically two semesters, three quarters, or equivalent) to be eligible.

Pre-completion OPT permits part-time work (20 hours/week maximum during school) in your field while you remain enrolled. Post-completion OPT, used after graduation, allows full-time work (no hour limits) directly related to your major for up to 12 months.

If you use part-time OPT before graduation, the duration of full-time OPT available afterward is reduced. One year of part-time (20 hours/week) pre-completion OPT consumes 6 months of your post-completion OPT allowance, leaving only 6 months of full-time work remaining.

A job offer is not required to apply for OPT , and your employer does not need to sponsor you. You must file Form I-765 with USCIS via your school's International Student Office. Standard processing takes 90 to 120 days.

STEM OPT extension: 24 additional months

Graduates with degrees in Science, Technology, Engineering, or Math are eligible to apply for a one-time, 24-month STEM OPT extension . This brings total OPT to 36 months (3 years) for STEM graduates.

You are eligible if your primary or secondary major is STEM-designated, you have not previously received a STEM extension on the same degree level, and your degree is at the bachelor's, master's, or doctoral level.

File your STEM OPT extension within 90 days before your current OPT EAD expires and no more than 60 days after your DSO enters the recommendation in SEVIS. If you file timely and USCIS receives your application before your EAD expires, you continue working for up to 180 days while your extension application is pending .

Unemployment limits during OPT

During post-completion OPT, you are permitted 90 days of unemployment . Exceeding 90 days of unemployment during initial post-completion OPT terminates your authorization and ends valid F-1 status.

If you qualify for STEM OPT, the regulations grant an additional 60 days of unemployment during the STEM extension period, for a total of 150 calendar days combined across post-completion OPT and STEM OPT. Days accrued during post-completion OPT count toward this combined limit. Once all 150 days are exhausted, transferring to a new F-1 academic program is not permitted, and the 60-day grace period for departure preparation is forfeited.

Unemployment days are counted from the start date on your EAD card regardless of your physical location.

Curricular Practical Training (CPT)

CPT authorizes internships forming part of your degree program requirements. You must have been in F-1 status for at least one full academic year to be eligible, though graduate students in programs requiring first-semester internships are sometimes permitted to apply earlier.

Your school's DSO must certify the training is integral to your curriculum. A job offer is required before requesting CPT authorization, unlike OPT, where no offer is required.

CPT work is limited to 20 hours per week while school is in session , with full-time work permitted during official breaks.

A critical restriction: full-time CPT of 12 months or more eliminates OPT eligibility entirely . Part-time CPT does not affect OPT.

Economic hardship work authorization

For students facing severe, unforeseen financial hardship, the school's DSO recommends and USCIS authorizes off-campus work. Qualifying circumstances include loss of financial aid through no fault of the student, substantial currency exchange rate changes, unexpected tuition or living cost increases, medical bills, or changes to the source of support.

You must have been in valid F-1 status for at least one full academic year, be in good academic standing with a full course load, and have exhausted on-campus employment options.

Work is temporary and limited to part-time hours during the academic term until the qualifying circumstances improve.

Application process and fees

To apply for OPT or other off-campus EAD authorization, consult your school's International Student Office or Designated School Official (DSO) per USCIS guidance on OPT . Your DSO endorses your Form I-20 and submits a recommendation in SEVIS.

You then file Form I-765 (Application for Employment Authorization) with USCIS within 30 days of the DSO endorsement. Always confirm the current OPT-specific filing total on the USCIS Fee Schedule (G-1055) or the USCIS Fee Calculator , since the base I-765 fee, the online/paper differential, and the applicable asylum-program surcharge introduced under the April 2024 USCIS fee rule have been further updated by the 2025 H.R. 1 fee changes.

Premium processing is available for $1,685 (as of March 10, 2025) , with a commitment to adjudicate within 30 business days. After USCIS approves your application, the physical EAD card is typically produced and mailed within roughly 1 to 4 weeks per USCIS guidance on card delivery timing .

Policy changes in 2025

In October 2025, the Department of Homeland Security eliminated the automatic 540-day extension of EAD validity for most employment-based immigration categories. However, this change does not affect F-1 OPT or STEM OPT students . F-1 students approved for STEM OPT extensions continue to receive a 180-day extension of work authorization based on timely filing.

USCIS also implemented a reduction in maximum EAD validity from five years to 18 months for certain adjustment-of-status and asylum applicants, effective December 5, 2025, but this does not apply to F-1 OPT categories.

Common application pitfalls

Working without authorization before EAD approval. Your DSO's endorsement and SEVIS notation are not authorization to work; only a valid, approved EAD card authorizes employment.

Exceeding work hour limits. Any hours over 20 during the academic term constitute a violation for on-campus work.

Accumulating more than 90 days (or 150 days with STEM extension) of unemployment. Once this threshold is crossed, authorization terminates and F-1 extension or transfer is no longer available. Related: F-1 EAD work authorization and tracking your SEVIS status.

Accepting CPT work outside the school's authorized duration. Always verify exact dates with your DSO.
