What Is OPT in the USA
OPT is a temporary employment authorization that allows F-1 international students to work in the USA in a job related to their major field of study. OPT can be used either during studies or after graduation, depending on student preference and eligibility.
The main purpose of OPT is to help students gain practical experience that complements their academic learning.
Types of OPT
There are two main types of OPT available to international students.
Pre Completion OPT
Pre Completion OPT is used while the student is still studying.
Key points:
Students can work part time up to 20 hours per week during academic sessions
Full time work is allowed during official breaks
Any time used in Pre Completion OPT is deducted from total OPT duration
Most students prefer to save OPT for after graduation.
Post Completion OPT
Post Completion OPT is used after completing the degree.
Key points:
Students can work full time
The job must be directly related to the field of study
This is the most commonly used OPT option

The standard OPT duration is 12 months.
This applies to:
Associate degrees
Bachelor degrees

Doctoral degrees
Students are eligible for 12 months of OPT at each higher education level. For example, a student who completes a master degree is eligible for OPT even if they used OPT after a bachelor degree.
What Is STEM OPT Extension
Students who graduate from a STEM designated program are eligible for an extended OPT period.
STEM OPT Duration
STEM graduates can extend OPT by 24 additional months, making the total OPT duration 36 months.
