An F-1 student must show an ability to afford the costs of school and living expenses before entering the United States and should not plan to work off-campus. U.S. Citizenship and Immigration Services (USCIS) will authorize off-campus employment only in cases of severe economic hardship occurring after a student's enrollment in an academic program and after the student has been in F-1 status for at least one full academic year, or in emergent circumstances as defined by the Department of Homeland Security (DHS).

  1. failed to properly report your arrival to your school's Office of International Services (OIS)
  2. engaged in unauthorized employment
  3. failed to report optional practical training (OPT) employment or accrued 90 days or more of unemployment while on OPT
  4. submitted fraudulent financial documentation to either obtain your student visa or extend your Form I-20
  5. entered into a scam marriage to get a green card
  6. either withdrawn from all classes or dropped below a full course load without advance permission from your DSO or OIS, failed to enroll in classes, or enrolled in too many online classes, or
  7. gotten expelled or suspended from school.
