What Kind of Letter Do You Need?
The Office of International Student & Scholar Services has changed its letter policy. OISSS no longer writes enrollment or visitation letters.
The only types of letters OISSS will continue to write are enrollment letters for a Canadian visitor visa, F-2/J-2 dependent visa letters, and detailed enrollment letters for Embassies or banking institutions. If you need one of these letters please contact OISSS.
Department of State requirements regarding the F-1 visa can be found here.
