So my plans are to go to Thailand (get visa on arrival) for one week and then go to Vietnam/Cambodia for 2 weeks. Then return to Thailand. Will I have 30 days on my Thailand visa from when I entered the first time or from the second time? Thanks
TLDR : Answer Summary
The duration of your visa on arrival in Thailand starts from the date you first enter the country. If you enter Thailand on a visa on arrival for one week, you will get 30 days from that entry. If you then leave Thailand and return after visiting Vietnam or Cambodia, you will not receive an additional 30 days; instead, you must adhere to the visa regulations assigned based on your first entry.
