Anyone here heard of a 1 year marriage visa (I've not)? From my understanding... Its NOT a 12 month extension of stay based on marriage issued by immigration on your non-o visa, nor is it a 12 month valididy non-o multi entry visa issued outside of Thailand. It is a 'final marriage visa' issued in Thailand by immigration, renewable annually, no 90 day border runs needed. This is news to me, Thanks.
