S3 Q&A: Should I start my SEVIS transfer as soon as I'm admitted?
Not automatically - the release date is chosen, not triggered by the offer. If you're working on OPT, releasing early stretches the time you can't work; if you're still studying, the date usually follows the end of your current term - either way it must fit the window your new school requires and any grace period. Your new school's counselor sends its transfer timing, and your consultant sets the exact date with you before you ask your DSO.
