i'm in the same situation. i only recently decided on ER after being set on another field. i've only looked into california programs, and i would say 50% of them have the deadline stated on their site. the deadline varies, standford said that if u are not complete by nov 1st to forget about it (absolute deadline). a couple others said that they will continue to accept applications past their deadlines but that that only means u are not guranteed an interview. a few schools had december as their deadline. again this is from a sample of bout 8-9 er programs in CA i looked into.
