Just a piece of information for anyone planning repeated use of visa-exempt entry into Thailand. Today I used that method the second time in about two months (receiving 45 days each time), but this time, at DMK airport, it caused some concern among the Immigration officers, who kept me in suspense as they consulted for maybe 10 minutes. They gave me the 45-day stay but told me to first apply for a tourist visa before coming again. Some of the posts that I see imply repeated visa runs are no problem, but I am skeptical about that...
