For F-1 international students in the U.S., gaining practical work experience is essential for both academic and professional development. To support this, the U.S. government offers two key work authorization options: Curricular Practical Training (CPT) and Optional Practical Training (OPT).
CPT enables students to participate in work opportunities directly linked to their academic programs, such as internships or cooperative education. On the other hand, OPT provides broader flexibility, allowing students to gain hands-on experience in roles related to their field of study, either during or after completing their degree.
This article simplifies the differences between CPT and OPT, covering their unique features, eligibility requirements, and application processes. It aims to help F-1 students make well-informed decisions about which option best aligns with their academic journey and career goals.
What is Curricular Practical Training (CPT)?
Curricular Practical Training (CPT) is a work authorization program for F-1 international students in the U.S., enabling them to gain practical experience directly related to their academic curriculum. It is designed to integrate employment opportunities, such as internships or cooperative education, into a student’s degree program.
- Purpose: Allows students to participate in work experiences, such as internships, practicums, or co-ops, that are an integral part of their academic curriculum.
- Eligibility: Students must maintain valid F-1 status and have completed one full academic year of study (exceptions exist for graduate students if required by their program).
- Connection to Curriculum: The work experience must be tied to a course or degree requirement.
- Type of Employment: Can be part-time (20 hours or less) during the academic term or full-time during school breaks.
- Approval Process: Requires authorization from the school’s Designated School Official (DSO) and must be mentioned on the student’s Form I-20.
- Employer Specific: Students can only work for the employer and in the position approved under CPT.
- Paid or Unpaid: CPT can include both paid and unpaid positions, as long as they meet the academic requirement.
- Duration: No fixed limit, but students who use 12 months or more of full-time CPT lose their eligibility for OPT.
Note: CPT helps students gain real-world skills while completing their degree, ensuring the experience aligns closely with their academic program.
What is Optional Practical Training (OPT)?
Optional Practical Training (OPT) is a work authorization program for F-1 international students, allowing them to gain practical work experience related to their field of study. OPT provides more flexibility compared to CPT, as it is not tied to specific academic courses.
- Purpose: Allows students to work in jobs directly related to their major field of study, helping them apply classroom knowledge in real-world settings.
- Eligibility: Available both before graduation (pre-completion) and after graduation (post-completion). Requires students to maintain valid F-1 status and complete at least one full academic year of study.
- Duration: OPT offers up to 12 months of work authorization, with a 24-month extension available for F-1 students in STEM fields (Science, Technology, Engineering, Mathematics) for post-completion OPT.
- Flexibility: Unlike CPT, OPT is not tied to a specific academic course, allowing students to work in a broader range of jobs related to their degree.
- Approval Process: Requires approval from USCIS (United States Citizenship and Immigration Services).
- Work Hours: Pre-completion OPT is part-time (20 hours/week) during the academic term and full-time during breaks, while post-completion OPT is typically full-time (40 hours/week).
Note: OPT offers greater freedom in job selection, making it an attractive option for students seeking to enhance their career prospects in the U.S.
