Pursuant to the Executive Order on Protecting the Nation from Terrorist Attacks by Foreign Nationals signed on January 27, 2017, the Department of State has temporarily stopped scheduling appointments and halted processing of immigrant visa applications for individuals who are nationals or dual nationals of Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen.
The National Visa Center has cancelled all scheduled immigrant visa interviews for these applicants scheduled in February 2017. This includes all visa categories, whether they are family- or employment-based. Applicants for fiancé visas (“K” visas) are included. We apologize for any inconvenience this causes. Once it is appropriate, the National Visa Center or a U.S. Embassy or Consulate abroad will notify you of a new interview date and time.
If you received an interview appointment in February and have not yet attended the required medical exam, please cancel your medical examination appointment. Medical exam results are only valid for six (6) months and we cannot predict when your visa interview will be rescheduled. When the National Visa Center or U.S. Embassy is able to reschedule your interview, they will contact you.
The National Visa Center will continue to work on in-process cases for these applicants up to the point of the interview. You should continue to pay fees, complete your Form DS-260 immigrant visa application, and submit your financial and civil supporting documents to NVC. NVC will review your case file and can qualify your case for an appointment. However, you will not receive a visa interview until further notice.
