Depends. Are you asking about getting the visa from a Thai embassy or from within Thailand? It can be tricky in Thailand if your marriage isn't already registered in Thailand.
seems like two agents who specialize in getting licenses from this office are saying the same thing. I don't think it's a misunderstanding. Seems like a deliberate policy change, possibly because of these agents. I'd guess Pattaya issues more foreign licenses than anywhere else, except maybe Bangkok.
