Thanks Pcee and Tasse for your replies.
"Once RFE response is received by BCIS one can go to local BCIS office and get iEAD provided 90 days passed"
Hi Pcee just to make sure , 90 days from the EAD's reciept date, correct ?? (and not from the day they received the RFE response)
I also looked up on BCIS website and here is the info that I found.
" If BCIS does not approve or deny your Employment Authorization Document application within 90 days , you may request an interim Employment Authorization Document. You must go to your local BCIS office and bring with you proof of your identity and any documents that BCIS has sent you about your employment authorization application. "
So looking at the above paragraph(approved or denied) ,it seems that they should give us an iEAD if we have replied to RFE.
