I carry a Maltese passport. I entered Thailand in mid January with a 60 day visa, which has expired. I am in Malaysia now but will have to enter Thailand again for my (April 18th) return flight to Malta. I am kindly asking knowledgable members help to suggest my best options.
TLDR : Answer Summary
As a Maltese passport holder, upon re-entering Thailand, you are eligible for a 15-day visa on arrival, which costs 2000 baht and is non-extendable. It is advised to enter Thailand after the 5th of the month to ensure you have enough time before your return flight to Malta.
