My friend is on a UK passport he had 4 entries into Thailand in 2019 his visa is about to run out if he comes goes to another country and get tourist visa from the Thai embassy in another country could he have problems coming in at the airport
TLDR : Answer Summary
A UK passport holder, who has made four entries into Thailand in 2019 and is about to run out of visa options, may face challenges re-entering the country. It is recommended that he applies for a tourist visa from a neighboring country such as Laos or Vietnam, as immigration regulations have become stricter. The specifics of his previous entries (whether they were visas or visa exemptions) and the details regarding his stay will impact his re-entry experience. The final decision will depend on the immigration officer's assessment when he arrives in Thailand.
