Ihave been back on the Thai Embassy website and it was the Long Stay visa ( O-A Non Imm ) that last year asked for a medical policy ( for the first time ever ) whilst in Thailand. However, it is now removed for the one year visa but still therefor the 5 year long stay visa. So I will now be applying for the 1 year long stay for my return in October. ( Glad i checked it ).
