Is it necessary for me to send documents AFTER submitting an application, so the AO would create my file? I am just wondering because if I’d apply EA, I’d like the documents to arrive by Nov 1 so the AO can start deliberating.
no you can start to do it now .
colleges will open up a file on you when they receive material such a SAT scores, LOR’s, . etc etc
but they wont look at your file until everything that they require has been submitted.
Its your job to stay on top of that.
Colleges frequently receive test scores and supporting documents before the app is filed. They are used to it.
