Submit EA application before October 1 and FAFSA?

Could someone explain whether it is OK to submit an EA application prior to the October 1 FAFSA date? I want to get as many applications submitted / filled out as possible before the beginning of senior year and the return of never ending work.

Will EA colleges admit through rolling admissions if the FAFSA hasn’t been submitted? I have searched high and low for the answer to these questions and can’t seem to find the any explanation about how it works. Advice pls!
Thank you!

You don’t need to fill out the FAFSA before submitting apps.

Related note: some schools also require submission of their own FA applications in addition to FAFSA.

You can edit and update FAFSA after submission.
