What is OPT and CPT in USA
🇺🇸 Introduction
If you are an international student studying in the USA on an F1 visa, you’ve probably heard about OPT and CPT. These two terms often confuse students who want to work while studying or after graduation.
In simple words:
OPT (Optional Practical Training) – allows you to work after or during your studies.
CPT (Curricular Practical Training) – allows you to work while studying.
Let’s understand in detail what OPT and CPT mean, their eligibility, process, and major differences so you can choose the right one for your career.
💡 What is OPT in USA? (Optional Practical Training)
OPT full form: Optional Practical Training
OPT is a type of temporary work authorization given to F1 students who want to gain practical experience in their field of study.
There are two types of OPT:
Pre-Completion OPT:
- You can apply while still studying.
- You can work part-time (20 hours/week).
Post-Completion OPT:
- You can apply after finishing your course.
- You can work full-time for up to 12 months.
If you’re a STEM (Science, Technology, Engineering, Mathematics) student, you can also apply for a 24-month extension, making it a total of 36 months (3 years) of work authorization.
🧾 OPT Eligibility:
- Must have valid F1 visa status.
- Must have completed at least one academic year in the U.S.
- Job must be directly related to your major field of study.
⚙️ OPT Application Process:
- Get recommendation from your Designated School Official (DSO).
- File Form I-765 with USCIS for work authorization.
- Receive your EAD card (Employment Authorization Document).
- Start working after your OPT start date.
🏫 What is CPT in USA? (Curricular Practical Training)
CPT full form: Curricular Practical Training
CPT is a program that allows international students to work off-campus as part of their course curriculum.
This is typically used for internships, cooperative education programs, or training projects that are part of your degree.
🧾 CPT Eligibility:
- You must be on a valid F1 visa.
- You must have completed one academic year before applying.
- The training or job must be part of your course curriculum.
- You must get authorization from your DSO before starting work.
⏰ CPT Duration:
There is no official limit to how long you can do CPT, but:
You lose your eligibility for OPT after completing 12 months of full-time CPT.
So plan carefully!

🧭 OPT and CPT for F1 Students
Both OPT and CPT are designed to help F1 students gain real-world experience related to their field of study.
However, many students get confused about Day 1 CPT, which is offered by some universities allowing you to work from your first semester.
⚠️ Note: USCIS carefully reviews Day 1 CPT usage. Always ensure your university is accredited and authorized to issue I-20s with CPT.
🧑💻 Example Scenario
Let’s say you are pursuing a Master’s in Computer Science:
During your second semester, your university requires an internship → You apply for CPT.
After graduation, you get a full-time job at a tech company → You apply for OPT to work legally.
If your job is in the STEM field, you can extend your OPT for 24 more months.
