Tourist visa requirements for Vietnam can change over time, so it’s essential to check with the official website of the Embassy of Vietnam or the nearest Vietnamese consulate for the most up-to-date information. However, I can provide you with general guidelines how to get tourist visa Vietnam:

1. Visa Types: Vietnam offers various types of tourist visas, including single-entry and multiple-entry visas, for different durations. Make sure you choose the one that suits your travel plans.
2. Visa Exemption: Check if your country is eligible for visa exemption. Some nationalities can enter Vietnam for a specified period without a visa. However, the duration allowed may vary.

You’ll receive this letter, and upon arrival in Vietnam, you’ll get your visa stamped at the airport.
