Can someone give me some advice please
I wish to come to Thailand as a tourist in the first week of September on a return flight returning the middle of January.
I am planning to stay for two months in Thailand and then one month or two in Vietnam as I have never been there.
the last time I was on holiday in Thailand was last September but that was just on a three week holiday on a 30 day visa-exempt. I have a total of three visa exempts over the last 3 years.
Can I fly in on my 30 day UK visa Exemption then extend for 30 more days then fly to Vietnam before returning back to Bangkok to catch my flight back home to London?
I want to purchase my ticket to Vietnam nearer the time as I'm not sure of the exact day I want to travel yet and I also will be getting a three-month visa letter. I will have a flexible return from Thai airways so I can move my return date forward or backwards depending on my plans.
Will I have any issues boarding the plane at Heathrow or at immigration in Bangkok or will they just see I have a return flight and not have an issue with the return date being January?
or
do I need to have my return flight for the beginning of December to keep it in 90 days and get myself a SETV from London?
I'm not sure how long it takes to send your passport to London and receive the SETV inside back in the post with the new online application system.
TLDR : Answer Summary
The user wants advice on traveling to Thailand as a tourist with a 30-day visa exemption, extending for an additional 30 days, then visiting Vietnam before returning to Bangkok. They are unsure about immigration and airline boarding regulations regarding their return ticket's date and whether they need a SETV visa.
