Tourist visas are available as single-entry one month visas and multiple entry three month visas. Double-entry visas can cost twice as much, but fees vary from country to country and can fluctuate over time. Contact the Vietnamese consulate in your country find out the cost of applying for a visa (see References). The required materials and documents for a tourist visa are:
-A passport valid for at least the next 6 months
-2 color passport-sized photos
-completed application forms
-application fee
A business visa is a three month multiple entry visa giving the holder the permission to do business and/or work in Vietnam. Business visas can be applied for after arriving in Vietnam on a tourist visa.
In addition to the requirements for a tourist visa, a business visa requires a letter of employment from your employer in Vietnam and/or a letter from your employer sponsoring your trip to Vietnam.
Student visas can be arranged after entering the country on a tourist visa or before entering the country. Like the business visa they are three month multiple entry visas.
A student visa application has the same requirements as a tourist visa, as well as proof or enrollment in classes in a Vietnamese school. Schools in Vietnam can offer help with changing tourist visas into student visas.
A diplomatic or official visa application has the same requirements as a tourist visa, except that fees are usually not required. In addition to the requirements of a tourist visa, diplomatic and official visas require an official letter from your government, embassy, consulate or organization outlining your status and reason for traveling to Vietnam.
