CPT: Rules and Best Practices for F1 Students

Quick Summary:

Curricular Practical Training (CPT) allows F1 visa holders in the U.S. to gain work experience related to their field of study. This guide covers CPT rules, best practices, timelines, and how to stay compliant with USCIS policies while preparing for future transitions like OPT or H1B.

What is CPT?

Curricular Practical Training (CPT) is a form of temporary work authorization for F1 students in the U.S., enabling them to engage in employment that is an integral part of their academic curriculum. This includes internships, co-ops, or practicum experiences.

F1 Visa: A non-immigrant visa for students enrolled in U.S. institutions.

CPT: Must be part of a course or a degree program and approved by your university’s Designated School Official (DSO).

CPT Rules for F1 Students

Understanding CPT rules is critical to maintaining F1 status and avoiding issues with future visa applications such as H1B or Green Card filings.

1. Eligibility Requirements

  • Must be enrolled full-time for at least one academic year in a SEVP-approved institution.

  • CPT must be directly related to the student’s major.

  • Must have a job offer before applying for CPT.

2. Types of CPT

  • Full-Time CPT: More than 20 hours/week. Note: Using 12 months or more of full-time CPT eliminates your eligibility for OPT.

  • Part-Time CPT: 20 hours/week or less. No impact on OPT eligibility.

3. University-Driven Approval

  • CPT must be authorized by the university through the DSO in SEVIS (Student and Exchange Visitor Information System).

  • CPT is issued on a new Form I-20 showing employment authorization.

Best Practices to Follow While on CPT

1. Always Get Written Authorization

Work must be authorized before starting. Working without CPT approval is a violation of F1 status.

2. Maintain Strong Documentation

Keep the following:

  • Offer letter specifying role, dates, and responsibilities

  • Course syllabus or university letter connecting CPT to curriculum

  • Updated I-20 showing CPT approval

3. Track Work Hours Accurately

Especially if you're on part-time CPT, ensure that your hours do not exceed 20 hours per week.

4. Don’t Use CPT as a Loophole

Avoid using CPT as a long-term employment workaround. USCIS scrutinizes misuse, which may hurt future H1B or Green Card filings.

Real-Life Scenario: 

Raj was enrolled in a master's program in New Jersey and started working full-time CPT for over 12 months. When he later applied for OPT, his application was denied because he had exhausted his eligibility. Worse, his H1B application was flagged due to prior violations, complicating stamping during his visit to Hyderabad.
Takeaway: Don’t overuse CPT. Stick to genuine academic training.

Q: Can CPT be extended?

A: CPT is approved per semester or course. It can be re-authorized for a new term if the course continues.
