回复:想问各位大虾:I485 RFE for I693 medical 给多长时间
It's specific to your individual case, printed in the RFE letter.
Based on the type of evidence requested, RFE deadline can be anytime from 30 days to 84 days (plus 3 days if by mail) It will be printed in the RFE letter, and that date will be the deadline (anywhere from 30 to 84 days from issuance)
