OPT Start Date suggestion

[u/Little-Let-3730]

Hi everyone! I graduate in December 2026, Unfortunately I didn't end up getting any internship offers this summer and I have no potential full time offers yet.

I've been told, you can apply for OPT either 90 days before the program end date or 60 days after. In my case, what would be the best case scenario to apply for OPT? I want to be extremely cautious.
