What are the requirements and process for applying for a Non-Immigrant O marriage visa from the UK?

First and foremost I want to say that it's completely ridiculous to hire an agent, pay them 80,000 baht to do something that inevitably you will have to do yourself. Thai immigration hands out a worksheet telling you what you need to provide and the agent doesn't have any of these items unless the agent is your wife. Start with going to immigration ond obtaining the non immigration visa, grab the work sheet and start doing each item. You'll need photos of you standing with her family at her location and I mean the pictures better include a placard with the actual address attached to a stationary item preferably the house or the outer wall. She will have to get two neighbors (relatives) willing to meet with an immigration policeman at your location and give copies of their identification and a statement attesting that you have been living there. You will have to make a map showing the route from the immigration office to your stated location. Your foreign bank statements are irrelevant so dont waste time with those. You need to show a minimum of 400,000 baht in your thai bank account and you can never ever let that balance slip below the 400k or you will be denied so don't make a joint account with your wife under any circumstance or promises. There are many other hoops to jump through and those services can't do them for you so many up and use the 80k fee towards the 400k, remember their money has to be in your thai bank account 60 days before your marriage visa appointment, do not and say this with me, do not put your wife's name on your thai account, I don't care how much she beds and promises, don't do it. Even after you do all of these things and more, you will still have to do other things so pull your pa to up because it's an "E ticket" ride.

no he will not. He can still show on his 1st extention he has the funds to transfer into thailand he if he has just opened a Thai bank account and does not have 12 payments going into the bank

Steven Bungay so what you want to say is, you never applied for the 1-year extension of stay based on being married to a Thai wife. You want to stay (or hibernate) in Thailand for 5 months. You enter on a 90-days Non-Imm-O Married Visa, and before the 90 days admitted stay are up, you apply for the 60-days extension based on "family visit" for which you just need the marriage registry printout from the Amphur that shows your marriage is still alive and valid, and the company of your wife on the Immigration visit. Would have been cool if you had detailled it a bit further, but never mind, mai pen rai, thank you
