hi my wife had interview in Oman on May 28th CR1 . I went with her officer asked about five questions after that she said everything is good, but we are still waiting for clearance which we have not got yet and she gave us 221g . No documents were missing and gave blank 221g no email came yet . There is X by 221g . Are they doing a background check? We are confused what clearance they’re waiting for. How long does it take . MAY 28th was interview last case was updated on may 29th . Thanks in advance…
