The USA is one of the most preferred study-abroad destinations for international students, especially Indian students, due to its world-class education, advanced research facilities, and flexible work-opportunity options. Among these opportunities, OPT and CPT play a major role in helping students gain practical work experience and shape their careers.
As Brainerrsoverseas, a leading study-abroad consultancy in Delhi, we help students understand these terms clearly and assist them in making informed decisions about studying and working in the USA.
OPT (Optional Practical Training)

OPT is a provision offered to international students studying in the US on an F-1 visa. It allows them to work temporarily in a job directly related to their field of study. The OPT full form is Optional Practical Training.
When a student has “opted” for OPT, the opted meaning is simply that the student has chosen to engage in practical training related to their academic program.
Types of OPT
1. Pre-Completion OPT
Students may apply for Pre-Completion OPT after completing one full academic year.
- They may work part-time during the academic year (up to 20 hours/week).
- They may work full-time during vacation periods.
2. Post-Completion OPT
This allows students to work full-time in the USA after completing their academic degree. This is the most commonly chosen form of OPT.
Duration & STEM Extension
- Students typically receive 12 months of OPT.
- Students in STEM programs may be eligible for an additional 24-month extension, increasing the total OPT duration to 36 months.
This makes the USA highly attractive to students pursuing courses in technology, science, and engineering.
CPT (Curricular Practical Training)

CPT is another form of work authorization for F-1 visa students. The CPT full form is Curricular Practical Training.
PT permits students to take part in internships, co-ops, training programs, or practical work that is a formal part of their curriculum.
Key CPT Features
- Must be directly connected to your field of study.
- Approved by your university’s international office or DSO.
- Can be part-time or full-time, depending on academic rules.
- Commonly used during the academic course for hands-on experience.
About the CPT exam
Many students search for the term CPT exam, but there is no such exam. CPT is not a test — it is simply a work authorization.
