Myself and my Thai girlfriend are traveling from Bangkok to Da Nang Vietnam soon.Will we both need visas for this trip.

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 .

Looking for some advice and hopefully not to much abuse, left Thailand on the 27th 4 days before my 30 days were up and went to Vietnam and have my flight back to the UK booked from Hanoi on the 9th of January cause I thought I’d stay but to cut a long story short didn’t like it so have decided to fly back to chiang Mai today I know I want have any problem coming back into Thailand but my question is, will I be ok to enter back into Vietnam for my flight home or is there some sort of limitations on how many times you can enter the country with in a certain time even though I could prove I’ve got a flight out the country a matter of hours later, hope you guys can help I understand it’s nothing to do with the Thai visa side of thing but there’s a few people in here with a wave of information and advice, sorry for the long post just tanned two litres of beer 🍺🍺

I will arrive Bangkok in the late evening from Rome.with flight to Vietnam next morning via viết airlines.Do I need Thai visa for overnight transit?
