All applicants, including children, are required to pay the application processing fee which is appropriate to the type of visa. This payment is only made on the United States Embassy grounds through the Consular cashier. This payment may only be made with U.S. dollars with exact change. The U.S. Embassy has specific requirements (PDF 2.44 MB) for the condition of U.S. dollars. The Embassy will not accept U.S. dollars that are dirty, damaged, torn, marked, stamped, nor older than 1997. The Consular Section does not accept Uzbek soum for payment. Applicants should keep in mind that the visa application fee is not refunded in the event of a visa refusal.
