CPT vs. OPT: What’s the Difference?

On- and Off-Campus Work in the U.S.


International students in the United States often seek employment opportunities to gain experience and support their finances. However, strict visa regulations limit the types of jobs they can pursue. While some students work on campus without additional authorization, off-campus employment requires special permissions, mainly in the form of Curricular Practical Training (CPT) and Optional Practical Training (OPT).


Both CPT and OPT provide work opportunities for F-1 visa holders, but they differ in purpose, duration, and restrictions. Understanding these programs helps international students plan their careers strategically while staying compliant with U.S. immigration laws.


An Overview of the Process


Before diving into the specifics of CPT and OPT, it’s essential to understand the general process international students must follow to work legally in the U.S.:

  1. Check Eligibility: Students must confirm that their visa status allows them to apply for CPT or OPT.
  2. Obtain Authorization: While CPT requires approval from the student’s Designated School Official (DSO), OPT involves an application to U.S. Citizenship and Immigration Services (USCIS).
  3. Follow Time Limits: Both programs have strict timeframes for work authorization, and exceeding these limits can affect visa status.
  4. Work in the Right Field: Employment must be directly related to the student’s major field of study.
  5. Maintain Full-Time Enrollment: Except for certain OPT cases, students must remain enrolled in their academic programs while working.

Now, let’s explore CPT and OPT in more detail.


Curricular Practical Training (CPT)


What is CPT?


CPT is a work authorization that allows F-1 visa students to gain practical experience in their field of study while enrolled in school. It is often required as part of an internship, cooperative education, or other academic programs.


Key Features of CPT:


  • Tied to Coursework: Students can only participate in CPT if their school program includes practical work as a requirement.
  • Pre-Approval Required: The school’s DSO must approve the work experience before the student begins employment.
  • Employer-Specific: Students can only work for the employer listed on their CPT authorization.
  • Full-Time vs. Part-Time:
    • Part-time CPT (20 hours or less per week): Allowed while attending school.
    • Full-time CPT (over 20 hours per week): Permitted during school breaks or when the academic program allows it.
  • Affects OPT Eligibility: If a student works full-time CPT for 12 months, they become ineligible for OPT.


Optional Practical Training (OPT)


What is OPT?


OPT is a temporary work authorization that allows F-1 students to gain work experience before or after graduation. Unlike CPT, OPT is not tied to a specific academic requirement.


Key Features of OPT:


  • More Flexible Than CPT: Students do not need to complete OPT as part of their coursework.
  • Requires USCIS Approval: Unlike CPT, students must file Form I-765 with USCIS and wait for their Employment Authorization Document (EAD) before starting work.
  • Can Be Used Before or After Graduation: OPT is available both during and after a student completes their degree.
  • 120-Day Unemployment Limit: Students on post-completion OPT cannot be unemployed for more than 90 days (or 120 days if on STEM OPT).


Types of OPT


There are three main types of OPT:


1. Pre-Completion OPT


  • Available before graduation.
  • Students can work part-time (20 hours or less) while school is in session and full-time during breaks.
  • The time used for pre-completion OPT is deducted from post-completion OPT.


2. Post-Completion OPT


  • Begins after graduation.
  • 12-month maximum duration (unless extended for STEM degrees).
  • Work must be directly related to the student’s major.


3. STEM OPT Extension


  • Available for STEM degree holders (Science, Technology, Engineering, and Mathematics).
  • Adds an extra 24 months to post-completion OPT (totaling 36 months of work authorization).
  • Requires employment with an E-Verify registered company.


Final Thoughts: Choosing Between CPT and OPT


For students navigating the complexities of U.S. work authorizations, understanding CPT and OPT is crucial. Here’s a quick recap to help decide:
