I'm intending to fly out to Thailand on 15 November for 50 days so will need a, Tourist Visa.
Is it okay not to get the Tourist visa in UK, get to Thailand,and get 30 day extension for the required fee.
What happens at immigration when they see my return flight is 7 weeks away?
TLDR : Answer Summary
The poster seeks clarification on entering Thailand for a 50-day stay without a tourist visa from the UK. Comments suggest it's possible to enter on visa exemption for 30 days and extend for an additional 30 days within Thailand, but caution regarding airlines requiring return/onward tickets. Recommendations include either purchasing a flexible ticket for later travel or applying for a tourist visa before departure for peace of mind.
