The Embassy supports business travel to the United States by making the U.S. visa process as quick and transparent as possible.  We encourage Kazakhstani travelers to apply for U.S. visas 4-6 weeks before their planned departure to allow time for any special processing requirements or seasonal delays.  Most visas, however, can be issued in far less time.  For more information on U.S. visa requirements and validity, please follow one of these links: State Department Visa Website, United States Visas.gov, and U.S. Embassy’s Consular Section.
