An F-1 verification letter is a letter written by the DSO to verify a student's current active enrollment and F-1 status (please see the sample below). It's mostly requested by a bank or the DMV (Department of Motor Vehicles) office, sometimes by embassies.
To request the letter, please email email@example.com. Please allow at least 4 to 5 business days to process the request. Students who submit their requests will receive a notification when the process is done.
