Theres a very good FB group that specialise in Thai Citizenship. Almost no trolls.
If youve been married to a Tai for 3 years, held the same visa and extension there of for 3 years, had the same wp with same employer and pay tax for 3 years youthen qualify to apply for Citizenship and skip PR.
Have you actually gone in and spoken to immigration officers yourself? Without an agent? They're usually very helpful. I know agents make up ( lie) absolute BS just to frighten you and wring more money out of you. I had 1 agent in Phuket insist that its impossible to get a work permit on an extension based on marriage and id been working illegally for the past 4 years. Nut job! Go have a chat with the boys in brown with your thai husband and get the list direct. Good luck.
