Hello, can anybody please suggest in the following issue? My uncle got tourist visa based on my invitation letter, which says he will stay with us in Chiang Mai for his entire trip. His flight is from Calcutta, India to Chiang Mai via Bangkok. However, now he has changed his mind and would like to spend some time in Bangkok before coming to Chaing Mai. Will that be a problem, as his plan for Bangkok trip has not been mentioned in the invitation letter. Any suggestion will be much appreciated.
TLDR : Answer Summary
The question concerns whether a change in travel plans to spend time in Bangkok, despite an invitation letter indicating a stay in Chiang Mai, will affect the validity of a tourist visa. Responses indicate that once the visa is issued, the specified itinerary in the invitation letter is not strictly enforced, suggesting that he should not face issues entering or traveling within Thailand.
