At my interview I was told that my case has been suspended and the Embassy will send a request for revocation. What does that mean?
Your petition has been returned to the National Visa Center with a recommendation for revocation. This means that the consular officer who interviewed you had concerns about the relationship that was the basis for the petition. A final determination on your case will be made by USCIS in the United States.
 
Questions about a case that has been returned with a request for revocation should be referred to the USCIS office where the petition was filed originally. No appeal or reinstatement request will be processed at the U.S. Embassy.
