My H1B extension was filed with requested validity period of 4 months from Oct 2016 to Apr 10 2017(To recapture 6 yr max). Received an RFE for additional docs on Mar 20th 2017(Got time till June to respond) i-140 approved in Nov 2016 hence not used for H1B extension.
Question 1: Can i continue to stay after Apr 10 2017. Since REF is pending will 240 days rule apply?
Question 2: Can USCIS give approval for past dates. Example: On 5th May 2017 can they send approval notice with approval date Apr 10 2017. If yes, will my stay beyond Apr 10 considered "out of status"
