Hi asking for Ukrainian friend who want to visit Thailand: visa on arrival, how long can stay in here? Can get extension via border runs? If yes, Is there a limit on amount of border runs?
Friend is In Ukraine and has Ukrainian international passport, will travel to Poland to fly to Thailand.
TLDR : Answer Summary
Ukrainian nationals can enter Thailand under visa-exempt entry for 30 days and can extend their stay for an additional 30 days at a local immigration office for a fee of 1900 baht. They can re-enter Thailand via visa-exempt entry again for another 30 days, but land border crossings have a limit of two times per calendar year. In Phuket, Ukrainians can obtain a standard 30-day extension, and those with a letter from their embassy due to the conflict in Ukraine may receive further extensions without a current limit.
