Highly likely u would receive an interview, WHY, marraige GC with a criminal inadmissibility calls for the care of a DAO.

U can either ur waiver to a Service Center before the interview, or to the local office at the time of the interview. TSC likely would transfer the waiver to the local office. The waiver would be paid in the form of money order $265 (current) to DHS. Sometimes a receipt may not be provided by a local office.
