CPT rules for F-1 visa: What international students need to know

Learn More

Curricular practical training (CPT) gives F-1 visa students a valuable opportunity to work off campus and gain practical experience while completing their degree. However, CPT for international students comes with strict rules that you must follow to maintain your legal status. Understanding these requirements is crucial if you want to make the most of your time studying – and working – in the United States.

This article walks you through the essential CPT rules for F-1 visa holders, common pitfalls to avoid and how CPT fits into a broader plan for career development and immigration compliance.

What is CPT under the F-1 visa?

Curricular practical training (CPT) is a temporary authorization for F-1 students to participate in paid or unpaid internships, cooperative education programs or employment that’s an integral part of their academic program.

CPT must be directly tied to your major or field of study, either through a degree requirement or by earning academic credit.

Key facts:

  • Authorized by your university: You must obtain CPT approval from your Designated School Official (DSO) before beginning any work.
  • Specific to an employer and dates: CPT approval is job-specific; you cannot change employers without new authorization.
  • Tied to enrollment: CPT often requires registration in a related course for the semester during which you’re working.

Who’s eligible for CPT?

Not every F-1 student qualifies automatically. Here’s what the F-1 visa requirements look like for CPT eligibility:

Completed one academic year

Students must complete one full academic year (two semesters) of study at a SEVP-certified institution before applying for CPT. The exception is for graduate students whose programs require immediate practical training.

Offer of employment related to major

You must have a written job offer that clearly connects the role to your major. A general office job, for example, would not qualify if you’re studying biomedical engineering.

CPT must fulfill an academic purpose

You usually need to register for a course tied to your CPT employment or fulfill a specific academic requirement outlined in your degree program.

How CPT fits into your long-term career plan

Understanding student visa work restrictions is about more than following the rules. Using CPT wisely can help you:

Build professional experience early

Employers prefer candidates who already have U.S. work experience. CPT international student internships strengthen your resume and expand your professional network.

Position yourself for OPT success

When you transition to optional practical training (OPT) after graduation, having prior CPT experience can make you more competitive for full-time roles.

Plan for future visa sponsorship

Some companies use internships to evaluate candidates for long-term hiring and H-1B sponsorship. A strong CPT performance can lead directly to jobs for international students in the U.S..

Common mistakes international students make with CPT

Starting work without authorization

This is one of the most serious violations. Even working a single day before CPT approval is processed can cause immigration issues.

Misunderstanding part-time versus full-time impact

Students sometimes use full-time CPT casually without realizing that 12 months or more disqualifies them from OPT.

Accepting unrelated work

Taking a job that’s not clearly connected to your major risks denial of CPT approval – and can create problems later during OPT or H-1B applications.

Overlooking academic requirements

Skipping the CPT-related course (if one is required) can void your CPT authorization and lead to a loss of F-1 status.

Key CPT rules to follow

Following the proper curricular practical training rules keeps you compliant with your F-1 visa. Here are the essentials:

1. Apply and get approval before starting work

You must not begin employment until your DSO approves CPT and issues a new I-20 form noting your authorization. Working without authorization can jeopardize your immigration status.

2. Work only for the approved employer

Your CPT authorization lists a specific employer. If you want to change employers, locations or roles, you must submit a new CPT request.

3. Respect the work schedule

  • Part-time CPT: Work 20 hours per week or less during the academic term.
  • Full-time CPT: Work more than 20 hours per week, usually during vacation periods or when your program structure allows.

4. Protect your OPT eligibility

Using 12 months or more of full-time CPT eliminates eligibility for optional practical training (OPT). Part-time CPT does not impact eligibility for OPT jobs for international students.

5. Maintain full-time enrollment 

You must maintain full-time academic status while engaging in CPT, unless otherwise authorized.

6. Keep clear records

Save offer letters, course enrollment confirmations and CPT authorizations. You may need them later when applying for OPT, STEM OPT or work visas.

FAQs

Can I use CPT during my first year as an F-1 student?

No. You must complete at least one full academic year before becoming eligible for CPT unless your graduate program requires immediate training.

How does CPT affect my OPT eligibility?

Using more than 12 months of full-time CPT cancels your eligibility for OPT. Part-time CPT does not affect OPT eligibility.

Can CPT be used for unpaid internships?

Yes. Even unpaid internships require CPT authorization if the work would typically be paid or involves duties that benefit the employer.

Can I work for multiple employers under CPT?

Only if each employer and position is separately authorized and documented by your DSO.

Do I need to apply for a separate work visa for CPT?

No. CPT is authorized through your F-1 status and handled by your university, not U.S. Citizenship and Immigration Services.
