I have a 17-year old daughter (visa exempt) arriving on a return flight to stay with me on Friday for 10 days. Is she likely to get grief at immigration and what if anything, does she need to have with her?
TLDR : Answer Summary
A 17-year-old traveling to Thailand under visa exemption should prepare certain documents to ensure a smooth entry at immigration. While she is not likely to face significant issues, it's advised that she has around 20,000 THB or equivalent in cash, a return ticket, and proof of accommodation for at least the first night. Although these are legal requirements, many travelers report that they've not encountered inquiries for such documents. Utilizing a meet and greet service at the airport is also suggested for added ease.
