. I'm married to a Thai woman. If you have all the paperwork ,it's easy. You don't need an attorney. The reason I mentioned it is immigration here is famous for not understanding the rules themselves. You'll get different answers to same questions. If you meet all the paperwork requirements, it very straightforward, especially for a foreign wife, its tougher for foreign husband's because of the financial requirements. I don't know why it's that way... probably a cultural thing. I'm on my 4th yearly extension and the only headache I ever had was the money thing, which is something you don't need to worry about.
An attorney will at least explain the process clearly and give you a list of documents needed and forms to fill out.
