What are the requirements for a married man's visa extension in Thailand?

Does this include bedroom action?

This is the list for marriage extension in Chiang Rai. Where it says they want pictures, they also need bedroom picture now. No joke.

I would say your safest course of action IS

Take this fairy tale amnesty until the 31st of July,

bounce out and back in on your existing visa (if it's still valid then) to get a new 90 day entry stamp and just stay on it as long as you can.

Roger, in bangkok you can apply for a yearly extension when you have 45 days or less left on your current 90 day entry stamp from your Non-O.

There was a post on the Thai Visa Nation News FORUM in the visa sub forum that had the requirements listed for a yearly extension based on marriage BUT I'd say take your wife and swing by the immigration office and get the hand out. It's quite the list of documentation you need, as well as getting the letter from the bank, and update your bank book, photos, map to the house, marriage certificates, copies of relevant passport pages, thai wifes i/d, house book, lease, TM30, etc

If your current extension runs out September you can not go now, only 45 days prior. But perhaps I understand your question wrong.
