How can I change my visa-exempt stamp to a Non-O visa based on marriage in Thailand?

It is a three step process to go from a 60 day visa exempt entry, to first a 90 day Non-O visa based on marriage and then a year extension of stay based on marriage inside the country at the Bangkok Immigration office

You need to meet the proof of funds 400K baht in a thai bank account in your name only on the day you apply for the initial 90 day Non-O visa, you need the photos, map, copies, bank documents, marriage documents, wife's documents, your copies AND you need a minimum of 15 days left on your current visa exempt entry or the 30 day extension from that entry in order to apply

You go to Chaengwattana Section C-1 with your wife, all the documents, (from visa exempt to in country Non-O you want form TM87), you apply for the 90 day Non-O visa, you pay the 2000baht, you get a receipt that tells you to come back in 2 weeks. On that date you go back with the passport, they ink in a Non-O visa stamp it used and give you a new 90 day stamp

THEN you wait until your 400K baht is seasoned in your bank account for 2 months and have 45 days or less left on that 90 day stamp, get all new documentation, photos, map, bank stuff, wife's stuff etc, along with form TM7, go to Chaengwattana Section L-1 and apply for the yearly extension for 1900baht

You will get a 21 day under consideration stamp, on that date you show up with your passport and go to Section L-2 and they'll ink in the year extension, after that you buy a re-entry permit if you need to exit/re-enter (1000baht for single and 3800baht for multiple)
