Rather than summarizing what is going on with visa issuance in Turkey, I want to provide you with these useful Questions and Answers on the U.S. Embassy and Consulates in Turkey website:
The U.S. Embassy in Ankara and the Consulate General in Istanbul offer Non-Immigrant Visa interviews by appointment only. All visa applicants should follow instructions at www.usvisa-info.com to schedule an appointment.
Questions Regarding the Re-Opening of Limited Visa Services
Q. I already have a valid non-immigrant visa; can I use it?
A. Yes, individuals with valid visas may continue to travel to the United States.
Q. Have non-immigrant visa (NIV) interviews in Turkey resumed?
A. We have resumed processing non-immigrant visas, but only on a limited basis. Therefore, a reduced number of appointments will be available.
Q. I already have an upcoming appointment for a visa. Do I need to make another appointment or take any other action?
A. If you already have an appointment for a future date, and you have not been notified that it was cancelled, you do not need to take further action. You may verify your appointment by logging into to our website at https://ais.usvisa-info.com (https://ais.usvisa-info.com) . We look forward to seeing you on the interview date you previously selected.
Q. My appointment for a visa interview was cancelled. Can I reschedule my appointment?
A. Yes, if your appointment was cancelled, we invite you to please go back into the internet-based appointment system and choose any open date to schedule a new appointment. Here is the link: https://ais.usvisa-info.com/tr-tr/niv
Q. I have an upcoming visa appointment, but I would like to have an appointment on an earlier date. Can I do that?
A. First, check the calendar at the internet-based appointment system (https://ais.usvisa-info.com/tr-tr/niv) and see what is available. An earlier appointment may have opened since you last checked.
If earlier appointments are not available, and if you have urgent travel needs, you may qualify for an expedited appointment. To request an expedited appointment, you must log in to your profile at www.usvisa-info.com. Please click on Group Actions on the Appointment Summary Page, select Request Expedite, and explain in detail why you need an earlier appointment. A consular officer will review your request. If your request is approved, the officer will reschedule your appointment. You can see if your request was approved on the same website.
Q. I made a visa appointment outside of Turkey. What should I do now? Can I get a refund if I cancel this appointment?
A. If you have made an appointment for a visa at a U.S. Embassy or Consulate outside of Turkey, you can choose to keep that appointment or schedule a new appointment at either Embassy Ankara or Consulate General Istanbul. However, if you choose to now book a new appointment in Turkey, you will need to pay an application fee in Turkey; fees are not transferrable between countries, or refundable.
Q. What can I do if my request for an expedited appointment is denied?
A. You may apply for any type of non-immigrant visas at a U.S. Embassy or Consulate outside of Turkey, whether or not you maintain a residence in that country. Please note that an applicant applying outside of Turkey will need to pay the application fee for services in that country, even if a fee has previously been paid for services in Turkey. All fees are non-refundable. We recommend contacting the U.S. Embassy or Consulate first, to ensure they are accepting applications.
