What is the difference between F-1 CPT and OPT?

Curricular Practical Training (CPT) is authorized by your university DSO prior to graduation for internships required by your degree curriculum. Optional Practical Training (OPT) is authorized by USCIS via an EAD card for post-graduation employment in your major field of study.

Does full-time CPT affect post-completion OPT eligibility?

Under 8 CFR § 214.2(f)(10)(i)(A), accumulating 12 months (365 days) or more of full-time CPT completely eliminates your eligibility for post-completion OPT. Part-time CPT (20 hours/week or less) does not reduce OPT eligibility.

What is the H-1B Cap-Gap extension?

Under 8 CFR § 214.2(f)(5)(vi), Cap-Gap automatically extends F-1 status and OPT work authorization for students who have a pending or approved cap-subject H-1B petition with an October 1 start date filed by an employer before their OPT/grace period expires.

What are the unemployment day limits on initial 12-month OPT and 24-month STEM OPT?

Students on initial 12-month OPT are allowed a maximum of 90 cumulative unemployment days. Students approved for the 24-month STEM OPT extension receive an additional 60 days, allowing a total of 150 cumulative unemployment days over the entire 36-month period.

What is Form I-983 for the 24-Month STEM OPT Extension?

Form I-983 (Mentoring and Training Plan for STEM OPT Students) is an official agreement between the student and an E-Verify employer outlining specific learning objectives, supervision, and compensation. It must be submitted to the DSO before STEM OPT recommendation.

What is the Day-1 CPT risk for F-1 visa holders?

Using Day-1 CPT at non-tier-1 or unaccredited institutions triggers heightened USCIS scrutiny during H-1B or Green Card (I-485) adjudication. Applicants receive Requests for Evidence (RFEs) requiring proof of continuous lawful non-immigrant status and physical class attendance.

⚠️ Critical DHS Rule Change: End of Duration of Status (D/S)

On July 17, 2026, DHS finalized a new rule ending open-ended Duration of Status (D/S) for F-1 and J-1 students. Effective September 15, 2026, all new and current students are restricted to a fixed admission period (maximum of 4 years). If you need to switch programs, extend studies, or transition from CPT to OPT, you must apply to USCIS for an Extension of Stay before your 4-year limit is reached.

Curricular Practical Training (CPT) Rules

CPT is alternative work/study, internship, or cooperative education authorized by your university DSO (Designated School Official) under your F-1 visa. It must be directly related to your major field of study and be an integral part of an established curriculum.

The 12-Month CPT Trap: While you can work on CPT as long as authorized by your school, if you accumulate **12 months or more of full-time CPT** (over 20 hours/week), you **forfeit 100% of your eligibility for post-graduation OPT**. Keep your full-time CPT under 364 days total to protect your post-grad work rights. Part-time CPT (under 20 hours/week) does not impact OPT.

Post-Completion OPT Timeline (12 Months)

Standard Optional Practical Training (OPT) grants up to 12 months of employment authorization post-graduation. Timing your application is critical:

The 90-Day Pre-Graduation Window

You can apply for OPT as early as **90 days before** your program end date. Applying early is highly recommended due to standard 2-3 month USCIS processing backlogs.

The 60-Day Post-Graduation Deadline & 30-Day DSO Rule

Your application (Form I-765) must be received by USCIS **no later than 60 days after** your graduation date. Furthermore, you must submit it to USCIS **within 30 days** of the date your DSO enters the OPT recommendation in SEVIS.

The 90-Day Unemployment Limit

During your 12 months of standard OPT, you are allowed a cumulative maximum of **90 days of unemployment**. Exceeding this limit immediately terminates your F-1 visa status.

STEM OPT Extension (24 Months)

Students with qualifying Science, Technology, Engineering, or Math degrees can extend their OPT work rights for an additional 24 months (36 months total).

STEM Extension Compliance Rules:

Requirement	Rule Details
Employer E-Verify	Your employer must be enrolled in the federal E-Verify database. You must include their E-Verify ID on your I-765 form.
Form I-983 Training Plan	You and your employer must sign a detailed training plan (Form I-983) and submit it to your school's DSO. Do not mail Form I-983 to USCIS—the DSO reviews it to issue your new STEM I-20.
Filing Window & 60-Day DSO Rule	Apply up to 90 days before your post-completion OPT card expires. Your application must be received by USCIS before your OPT expires, and within 60 days of your DSO recommendation date.
Unemployment Buffer	STEM OPT grants an additional 60 days of unemployment, raising your total allowable limit to 150 days over the 36-month period.

🛡️ Understanding the H-1B "Cap-Gap" Extension

If your employer sponsors you for the H-1B visa and your petition is selected in the April lottery and filed as a "Change of Status" with an October 1st start date, you are covered by **Cap-Gap**.

* **OPT Expires Before October 1:** If your OPT card expires between April 1 and September 30, the Cap-Gap **automatically extends** both your legal F-1 status and your employment authorization until September 30, allowing you to continue working uninterrupted. * **OPT Expires During Grace Period:** If your OPT card expires before April but you are in your 60-day grace period when the H-1B is filed, your legal presence is extended, but **you cannot work** during the Cap-Gap.

Critical Cap-Gap Warning: Do not travel outside the U.S. while on a Cap-Gap extension. If you leave the country, you cannot return on F-1 OPT and your H-1B Change of Status petition will be abandoned by USCIS.

⚡ F-1 OPT Premium Processing (Form I-907) & Timeline Rules

If regular post-completion OPT processing is delayed and your job start date is approaching, you can upgrade your pending Form I-765 to Premium Processing (Form I-907) at any time online via your USCIS account.

USCIS Fee: $1,685 for F-1 OPT / STEM OPT (Form I-765 category (c)(3)).

F-1 Student Employment FAQ

How many hours can I work on campus during semesters?

You are legally limited to a maximum of 20 hours per week during active academic terms, and up to 40 hours per week during official school breaks.

What is the difference between CPT and OPT?

Curricular Practical Training (CPT) is for off-campus work *during* your degree program. Optional Practical Training (OPT) is for work *after* graduation.

If my OPT application has been pending over 3 months, is pushing my job start date by 5–6 weeks and applying for Premium Processing enough time?

Yes, absolutely. Filing Form I-907 guarantees USCIS adjudication within 30 calendar days. Adding a 7–14 day physical card production/delivery buffer means pushing your start date by 5 to 6 weeks gives you plenty of time to receive your physical EAD card before your first day of work.
