Status: Medical Student (Accepted) AMCAS states that it usually takes ~4-6 weeks for verification to go through, but looking at the verification trend right now here: http://forums.studentdoctor.net/threads/2014-2015-verification-thread.1076112/ I would say you're looking at 3-4 weeks from the time of submission.
Gringo, I assume that you will get the biometrics notice before your 3 months of filing have passed. It is required for the EAD and 3 months is the maximum time to wait for EAD before you can get it at walk-in thru infopass apointment with your local USICS office. My notice said EAD takes 30 to 90 days to process.
