Nationals of countries where the US does not provide routine visa services will need to apply at designated locations. For example, Afghans must apply in Islamabad, Cubans in Georgetown, Iranians in Dubai, Russians in Astana or Warsaw, and Venezuelans in Bogota.
The State Department cautioned that applicants who try to apply outside their country of residence or nationality may face longer wait times and more difficulty qualifying, with fees non-refundable and non-transferable.
