I'm studying at an US med school and on an F-1 visa. I plan to apply to a residency that requires a prelim/transitional year so I was going to use the OPT option on the F-1 visa for that year. Does anyone have any experience with the start and end dates for the OPT especially if I end up doing my PGY-2 at another institution? It looks like a lot of these prelim programs start mid June (for orientation) and end June 30th so that is actually a little more than a year.
