A little off topic. But anyone know if I can just fly to Vietnam from Thailand and get the visa on arrival without the invitation letter or i can get everything sorted out there? Tried the evisa but the website won’t let me get to the part where I pay for some reason .
TLDR : Answer Summary
The ability to obtain a visa upon arrival in Vietnam without an invitation letter largely depends on your nationality. Some travelers can enter visa-free for a limited time, while others, particularly U.S. citizens, must secure a visa in advance. Users have reported difficulties with the e-visa application process; accessing the official site can be problematic in Thailand, with some recommending the use of VPNs. Many suggest using a visa agent to avoid issues with online applications and recommend caution due to potential errors in issued visas. Ultimately, the original poster has decided to travel to Cambodia instead, indicating that the e-visa application for Cambodia was successful.
