  • Students should wait 7-10 business days after arriving in the U.S. and completing Immigration Document Review with ISSS before applying for a Social Security Number. This allows time for arrival data from the port of entry and SEVIS to be entered in the primary system that the Social Security Administration uses to validate authorization.
  • F-1 and J-1 visa students may work on-campus up to 20 hours total per week during the academic year and up to 40 hours total per week when classes are not in session. J-1 students must have their employment authorized in SEVIS and get an authorization letter from ISSS before beginning employment.
