Hi any one can advise me USCIS denied my case because they ask for RFE and my petitioner didn't check in account and the respond time expired and USCIS denied my case . please tell me can I appeal in this scenario??
You've posted this on your profile, best to post it again in the forums but do give more info so that people can help you - what kind of case, what the PD is, what country, and what the RFE was for.
