OPT vs CPT Visa Rules: Understanding F1 Work Eligibility and Restrictions

For F-1 international students in the United States, the distinction between Curricular Practical Training (CPT) and Optional Practical Training (OPT) defines nearly every work opportunity available before and after graduation. As of 2025, over 1.2 million F-1 students are enrolled in U.S. institutions (SEVIS 2024 Annual Report), and roughly 40% of them will use either CPT or OPT during their academic career. CPT allows work authorization while you are still enrolled in classes, typically after one academic year, and must be directly tied to a specific course or degree requirement. OPT, by contrast, offers up to 12 months of post-completion work authorization (with a 24-month STEM extension available for qualifying fields) and does not require a concurrent course enrollment. The U.S. Citizenship and Immigration Services (USCIS) and the Student and Exchange Visitor Program (SEVP) jointly enforce these rules, and violations — such as unauthorized off-campus employment — can result in termination of F-1 status. Understanding the eligibility windows, application timelines, and processing restrictions is essential for staying compliant and maximizing work opportunities while on an F-1 visa.

CPT Eligibility and Restrictions

Curricular Practical Training (CPT) is an F-1 work authorization that permits off-campus employment directly related to your major field of study. To qualify, you must have been lawfully enrolled on a full-time basis for at least one full academic year (two semesters or three quarters) at a SEVP-certified school. Exceptions exist for graduate programs that require immediate practical training from the start.

CPT must be an integral part of an established curriculum — typically listed as a course in the school’s catalog, such as a co-op, internship, or practicum. Your Designated School Official (DSO) authorizes CPT in SEVIS, and you cannot begin work until the authorization is issued. CPT can be part-time (20 hours or fewer per week) or full-time (more than 20 hours per week). Importantly, if you accumulate 12 months of full-time CPT, you become ineligible for OPT at that same degree level (8 CFR 214.2(f)(10)(i)). Part-time CPT does not affect OPT eligibility.

CPT Application Timing

Unlike OPT, CPT does not require USCIS approval — only DSO authorization. Processing time is typically 1–2 weeks, but some schools require 30 days lead time. You must have a job offer before applying, and the CPT end date must align with the course end date.

OPT Eligibility and Duration

Optional Practical Training (OPT) provides F-1 students with up to 12 months of work authorization directly related to their degree program. OPT can be used pre-completion (while still enrolled, part-time or full-time) or post-completion (after graduation). Pre-completion OPT reduces your total available post-completion OPT by the amount used — for example, 10 months of full-time pre-completion OPT leaves only 2 months of post-completion eligibility.

Post-completion OPT requires you to submit Form I-765 to USCIS with a $470 filing fee (as of April 2025). USCIS processing times average 3–5 months. You must apply within 30 days of your DSO recommending OPT in SEVIS and no later than 60 days after your program end date. During the 12-month OPT period, you cannot accrue more than 90 days of unemployment.

STEM OPT Extension

Students with a degree in a STEM field (science, technology, engineering, mathematics) from an accredited institution can apply for a 24-month STEM OPT extension, bringing total post-completion OPT to 36 months. The extension requires an employer that is enrolled in E-Verify and a formal training plan (Form I-983). Unemployment allowance during the STEM extension period is capped at 150 days total across both the initial 12-month OPT and the 24-month extension.

Key Differences Between CPT and OPT

Requirement	CPT	OPT
Authorization authority	DSO only	USCIS (after DSO recommendation)
Processing time	1–2 weeks typical	3–5 months typical
Job offer required before applying	Yes	No (for post-completion)
Maximum duration	No limit per degree level	12 months (36 with STEM)
Impact on future OPT	12 months full-time CPT = ineligible for OPT at same level	No impact on future CPT
Unemployment limit	Not applicable	90 days (150 with STEM extension)

Employment Restrictions and Compliance

Both CPT and OPT carry strict compliance requirements. For CPT, you may only work for the employer and at the location specified in your SEVIS record. Changing employers or job duties requires a new CPT authorization from your DSO. For OPT, you must report any change of address, employer, or unemployment status to your DSO within 10 days (8 CFR 214.2(f)(22)). Failure to report can lead to SEVIS record termination.

Off-campus employment without authorization is a common violation. Working even one hour without CPT or OPT authorization violates F-1 status. Similarly, working more than 20 hours per week on CPT while school is in session (unless your DSO authorizes full-time CPT) is a violation. USCIS has increasingly scrutinized CPT usage at third-party worksites — the employer must be the entity that provides the training, not a staffing agency.

Cap-Gap Extension

If your H-1B petition is selected and pending while your OPT ends, the cap-gap extension automatically extends your F-1 status and work authorization until September 30 of that year. This applies only to students with a timely-filed H-1B petition (change of status request) and a requested start date of October 1.

STEM Extension and Employer Requirements

The STEM OPT extension imposes additional obligations on both the student and the employer. The employer must be enrolled in E-Verify and remain in good standing throughout the extension period. The student and employer must complete Form I-983, which outlines the training goals, evaluation methods, and how the position relates to the STEM degree.

On-site supervision is mandatory — the training cannot be conducted remotely or through a third-party intermediary. USCIS requires that the employer assign a mentor or supervisor who is physically present at the worksite. As of 2025, USCIS has increased site visits to verify compliance, particularly for employers with multiple STEM OPT participants. The student must submit a self-evaluation every 6 months to the DSO.

Practical Planning Tips

• Start OPT application early: Submit Form I-765 as soon as your DSO recommends OPT in SEVIS. USCIS recommends filing at least 90 days before your program end date.
• Track CPT days carefully: If you plan to use OPT later, avoid exceeding 11 months of full-time CPT at the same degree level.
• Maintain valid passport: Your passport must be valid for at least 6 months beyond your intended stay in the U.S.
• Use the E-Verify employer list: Before accepting a STEM OPT job, confirm your employer is E-Verified via the official E-Verify website.
• Keep copies of all I-20s: Your DSO issues a new I-20 for each CPT or OPT authorization — retain every version for future immigration applications.

For international students managing tuition payments and living expenses while on CPT or OPT, some use platforms like Airwallex global account to hold multiple currencies and transfer funds between U.S. and home-country bank accounts with lower fees than traditional wire transfers.

FAQ

Q1: Can I work on CPT and OPT at the same time?

Yes, but only if you have separate authorizations for each. You cannot use the same job to satisfy both CPT and OPT requirements simultaneously. CPT requires concurrent enrollment in a course, while OPT does not. If you are authorized for part-time CPT during the academic year and also have approved post-completion OPT, you may hold two separate positions — one under each authorization — as long as total weekly hours do not exceed any school policy limits.

Q2: How many days of unemployment are allowed on OPT?

You are allowed a total of 90 days of unemployment during the initial 12-month post-completion OPT period. If you receive a 24-month STEM extension, the unemployment limit increases to 150 days total across both periods. Each day you are not employed or working at least 20 hours per week in a position directly related to your degree counts toward this limit. USCIS tracks unemployment through SEVIS records and your DSO reports.

Q3: What happens if my OPT application is denied after my 60-day grace period ends?

If USCIS denies your Form I-765 after the 60-day grace period following your program end date, you are considered out of status from the date of denial. You must depart the U.S. immediately or file for reinstatement (Form I-539) within 5 months of the status violation, though reinstatement is not guaranteed. To avoid this risk, apply for OPT at least 90 days before your program end date and ensure your application is complete with correct filing fees and supporting documents.
