As of September 08, the United States Embassy in Mongolia is resuming limited American Citizen services, certain Immigrant and Nonimmigrant visa services, including: students (F-1 / M-1), exchange visitors (J1), treaty investors (E-2), and certain immigrant visas that qualify under current Presidential Proclamations. While the Embassy aims to process cases as soon as possible, there is likely to be increased wait times for completing such services due to substantial backlogs. The MRV fee is valid and may be used to schedule an interview appointment in the country where it was purchased within one year of the date of payment. If you have an urgent matter and need to travel immediately, please follow the guidance provided at https://ustraveldocs.com/mn/mn-niv-expeditedappointment.asp to request an emergency appointment.
Applicants for H1B, H2B, H4, L and certain J categories covered by Presidential Proclamation 10052 should request an appointment only if you have reason to believe you may qualify for one of the exceptions listed in the Proclamation here: https://www.whitehouse.gov/presidential-actions/proclamation-suspending-entry-aliens-present-risk-u-s-labor-market-following-coronavirus-outbreak/.
