I would like to stay in Thailand for 2-3 months (may be some more). I have thai marriage certificate (+children birth certificate) and thinking to apply for 3 months NON-O visa to avoid TR visa because at the present time it’s a bit complicated to get it in Russia (its almost impossible to catch free slot in visa center to apply for TR visa, its necessary to provide paid accommodation for 3 months, return ticket etc..). So if someone have an experience in such kind of case I would be happy to get your advice.
