Hi! I did ask about this before but after talk to embassey in Oslo I am not sure what to do. Worry free travel told me to get a 60 days Multiple Visa. Going to Thailand for 29 days first, then 29 days Vietnam and after that 21 days in Thailand. Problem is Quatar Airways at the airport.... Got all ticket in and out from Thailand. Even show the ticket in airport I am not 100% sure. Anyone got a experience about this. Thanks.
TLDR : Answer Summary
The user is confused about their visa requirements for traveling to Thailand and Vietnam. They initially considered obtaining a 60-day multiple entry visa but were advised that they could enter Thailand visa-exempt for both visits, provided they have exit tickets to Vietnam and back to their home country. This advice was confirmed by several community members who emphasized the importance of having all flight tickets ready to present when traveling.
