F-1 Optional Practical Training

What is Optional Practical Training (OPT)?

OPT is a benefit authorized by U.S. Citizenship and Immigration Services (USCIS) that extends the F-1 student status to allow you to work in the U.S.A. in order to gain practical training in your major field of study.

  • An employment offer is not required to apply for OPT.
  • OPT must be directly related to the student's major field of study.

Eligibility Requirements

Students who have been in lawful, full-time student status for at least one full academic year are eligible for a total of 12 months of OPT. Any period of OPT used before the completion of the program is subtracted from the 12-month total limit. Students may be authorized for 12 months of OPT and become eligible for another 12 months of OPT when they change to higher education level (i.e., from Bachelors to Masters; from Masters to PhD). The 12-month total limit of OPT applies to each educational level (Bachelors, Masters, and Doctoral degree programs).

  • Only students pursuing a degree are allowed to apply for OPT.
  • Special non-degree students are not eligible to apply for OPT.

Students may apply for pre-completion or post-completion OPT

  • Pre-completion OPT, part-time or full-time, during the annual school vacations (e.g. summer vacation)
  • Pre-completion OPT, part-time only (max. 20 hours/week), while school is in session; no other on or off-campus employment is allowed
  • Pre-completion or Post-completion OPT, after completion of all course requirements but before completion of dissertation/thesis
  • Post-completion OPT, full-time, after completion of course of study

Application Deadlines

  • For Pre-completion OPT, not earlier than 90 days prior to being enrolled for one full academic year
  • For Post-completion OPT, within 90 days prior to and no later than 60 days after completion of the program

The USCIS Processing Center must receive the complete OPT application and all required documents (see below) before the final deadline, which is the 60th day from the official program end date. Failure to comply with this deadline will result in loss of the entire OPT benefit.

USCIS processing times can take as long as 3-4 months. Please apply as soon as possible to ensure that you receive Employment Authorization Document (EAD) on time. The EAD is the offical work permit issued by USCIS that allows you to be hired and work in the U.S.A. during OPT.
Important: Students are not permitted to begin employment until they receive the EAD and until the approved start date listed on the EAD.
