We went for our AOS marriage interview on august 18, 2011 in Baltimore USCIS office. the IO went straight to the interview steps, we were interviewed separated. we pretty much matched the answers which was based in our life together and personal information. The IO took the I-94 but not my EAD. At the end didn't say approved or not approved. Just wait for the mail. No updates online, no letters, it has been more than a month. What should we expect ? do we have to wait more time or contact them ? it's just such an anguish and permanent distress. Any input of similar experience will be greatly appreciated.
