Those applying to the US can pay the visa fees at the post office when they provide their CGI-Reference Number.
The post office will then transfer the visa fees to the relevant US agency involved in granting visas. Applicants do not pay the transfer fee.
The new regulation is applied for non-immigrant visa (DS-160) and finance visa (K). Visa applicants can get further information at the official website of the US Embassy in Vietnam and complete procedures online before paying the visa fee at the post office.
As from April 1, all visa applications must be sent through the post office service.
