This means the student may remain in the U.S. until the program end date provided they are otherwise maintaining their status. The student then has 60 days from
the program end date to leave the U.S. unless engaged in authorized employment.
While maintaining valid F-1 status, students may be employed on the campus of the school they are authorized to attend for a maximum of 20 hours per week while classes are in session.

term.

F-1 students experiencing unforeseen “economic hardship” may apply for off-campus work authorization. Employment on an EAD based on economic hardship can be on or off-campus, and is also subject to the same hour per week restrictions as for on-campus employment. F-1 students may participate in employment directly related to field of study by
obtaining practical training authorization. There are two kinds of practical training: i) Curricular Practical Training (CPT) during the course of study requires approval of DSO on Form I-20 and no EAD is required. CPT employment authorization is employer-specific; ii) Up to 12 months of Optional Practical Training (OPT) can be done during or after completion of studies.
