I've dealt with this before.

YOU MUST change EVERYTHING to what your REAL name & DOB is BEFORE marrying or applying for anything, and start with a clean slate. IE. You have NEVER left the country.

This happens more often than I am happy with, and it is the agencies taking advantage of desperate people, although you have to accept 50% responsibility for not thinking it through.

Hopefully you are married under your LEGAL documents and not any ILLEGAL ones, otherwise YOU ARE NOT MARRIED.
