Hello, I was wondering whether it's possible to enter Thailand on a visa waiver card from the UK and then upgrade to a visa of some kind, perhaps a 3-month tourist visa? I was considering visiting an immigration office after a week or so. Thanks in advance for any advice.
TLDR : Answer Summary
The discussion addresses whether someone from the UK can enter Thailand on a visa waiver and subsequently upgrade to a 3-month tourist visa. Multiple comments clarify that while it's possible to enter on a visa waiver, one cannot convert it to a tourist visa from within Thailand. It is recommended to apply for a 60-day electronic tourist visa before traveling or consider obtaining a non-immigrant visa based on eligibility.
