The USA has always been a popular study destination among international students for its wide variety of courses and post-study work opportunities. While studying, one of the main concerns of every international student is to find possible opportunities to put theory into practice and earn money to support them financially. This kind of hands-on experience can make a big difference on a resume.
To get this experience legally, students need to understand two key types of work permits: Curricular Practical Training (CPT) and Optional Practical Training (OPT). These two options let you work while you study or after you graduate. However, they are very different.
Many students feel confused about which option to choose and when. Misunderstanding their differences can lead to visa issues and affect your career plans. Misunderstanding their differences can lead to visa issues and affect your career plans.
This guide will simplify everything, helping you make the right choice for your academic journey and future career goals.
Understanding CPT and OPT: A Quick Overview
What is CPT?
Curricular Practical Training (CPT) is a temporary work authorization for international students on an F-1 visa. It allows you to gain hands-on experience while studying, through paid or unpaid internships, co-op programs and practicum.
The key word is “curricular,” meaning the work must be a major or integral part of your academic program. Since it’s tied to academics, you cannot use CPT just for any job, it has to be connected to your degree.
Students can apply for CPT after completing at least one academic year, and it requires authorization from the university’s Designated School Official (DSO). CPT is employer-specific and must be completed before graduation.
Your employer will have an agreement with your school and may offer part-time work (up to 20 hours per week) or full-time work (more than 20 hours per week). The key thing to note here is that if you work full-time for 12 months under CPT, you will lose your eligibility to apply for OPT.
What is OPT?
Optional Practical Training (OPT) is a flexible training program that gives students holding an F1 visa a chance to work in the USA for up to 12 months in a field related to their degree. OPT can be used before completing your program (pre-completion OPT) or after graduation (post-completion OPT). Unlike CPT, the authorization for OPT comes from U.S. Citizenship and Immigration Services (USCIS), not your school.
If you work while school is in session, you can take on up to 20 hours per week. However, all periods of pre-completion OPT will be deducted from the available period of post-completion OPT. The most common choice is post-completion OPT, which helps graduates kick-start their careers.
For students in STEM fields, there’s an additional 24-month extension, making the total duration up to 36 months. OPT is highly valued because it provides more flexibility in choosing employers and gaining real-world experience.
CPT vs OPT: Key Differences
While both CPT and OPT allow international students to engage in meaningful work experiences related to their course of study, these programs have some key differences. Here’s how they compare.
Understanding the main differences between CPT and OPT is crucial for smart career planning.
| Feature | CPT (Curricular Practical Training) | OPT (Optional Practical Training) |
| Eligibility Requirements | Must be on F-1 visa, completed at least one academic year, and the job must be part of the curriculum. | Must be on F-1 visa, can apply 90 days before program end, and work must be related to your degree. |
| Purpose | To gain practical experience before graduating to fulfill an academic requirement (e.g., an internship course). | To gain work experience in the same field after graduation. |
| Authorization | Requires permission from ISS (International Student Service) and the academic department (DSO) | Approved by USCIS with an Employment Authorization Document (EAD). |
| Timing | Must be completed before you graduate. | Can be done before (Pre-Completion) or after (Post-Completion) graduation. |
| Working part-time or full-time | Students can either work part-time (20 hours or less) or full-time (40 hours) | Generally, OPT is a full-time training done after graduation. For before graduation you can work part or full time. |
| Employment Duration | Tied to your program’s curriculum; can be part-time or full-time. Working 12 months full-time for CPT will mean you lose eligibility for OPT. | A total of 12 months per degree level. Students with a STEM degree get a 24-month STEM extension, making a total of 36 months. |
| Employer | Tied to a specific employer listed on your I-20. | Generally flexible; you can work for any employer as long as the work is related to your major. |
| Impact on Future Visa or Green Card Applications | Usually has no direct effect but must stay within F-1 rules. | OPT experience often helps students secure H-1B sponsorships, making it a first step toward getting a Green Card. |
When Should Students Choose CPT or OPT?
Now let’s clear your confusion regarding which one is a better option for you. Well, the choice between CPT and OPT depends on your academic program and career goals.
- Choose CPT: when your program requires internships, co-ops or practical training as part of the coursework. For example, an MBA student may take CPT for a summer internship with a company linked to the program. Thus, you can gain valuable hands-on experience in your field of study while still enrolled in their academic program.
- Choose OPT: if you want to launch your career after graduation. For instance, a Computer Science graduate might use OPT to work at a tech company right after completing their degree. There’s an advantage if your field of study is STEM, as it allows you to extend your OPT for up to 24 months more. This professional experience can make you a more attractive candidate for employers looking to sponsor an H-1B visa.
Application Process & Timelines
The application processes for CPT and OPT are very different.
How to Apply for CPT?
The CPT application is handled entirely by your university. You’ll need to secure an internship, get a letter from your employer, and have your academic advisor approve it. Your DSO will then review your application and, if approved, update your I-20 and SEVIS record.
Try to apply at least two weeks before you wish to start working, as the authorization process might take seven to 10 days. The process is much quicker.
How to Apply for OPT?
The OPT application is more formal and is submitted to USCIS. Students must make a request to the DSO (Designated School Official) to recommend the OPT. The DSO will then recommend it by endorsing the I-20 form. Students must file Form I-765 along with the required fee and the supporting documentation as given in the form instructions.
The filing period is very specific: you can apply up to 90 days before your program end date and no later than 60 days after. USCIS processing times vary but can take several months, so it’s critical to apply early. You can start working after USCIS issues your Employment Authorization Document (EAD).
Benefits and Limitations of Each
As two sides of a coin, there are both advantages and disadvantages for both CPT and OPT.

CPT Limitations:
- Tied to Curriculum: The work must be directly related to your degree program and is often restricted to specific courses or requirements.
- Can Affect OPT: As mentioned, using too much full-time CPT (12 months or more) makes you ineligible for OPT.
OPT Benefits:
- Flexible: You have more freedom to choose your employer and job, as long as it’s in your field.
- Career Launch: It’s the primary way for international students to start their careers and gain valuable post-graduation work experience.
- Pathway to H-1B: It’s often the first step for students who want to apply for a long-term work visa like the H-1B.
OPT Limitations:
- Time-Sensitive: You only get 12 months (or 36 for STEM majors), and the clock starts running after graduation.
- Unemployment Rule: You are limited to a total of 90 days of unemployment during your standard 12-month OPT period.
- Application process time: The process is long and needs USCIS approval, so it is may take several months.
