recently, in the last few years, when both are over the 50+ year retirement age, Thailand has wanted both partners to have their own visa extension, not one being on a dependent visa extension, which means you'll both need bt800,000 in your bank accounts. Keep in mind that the OA retirement visa will require Thai approved health insurance, and Medicare isn't valid out of the US.
there is no "3 times". All limits ended last July when the 30 day visa exempt entry was extended to 60 days, and before that the limit was 2 border crossings, not 3. You are filled with lots of BS misinformation. There is no 90 day non-immigrant visa you would qualify for. The 90 days of a tourist visa is how long it is valid for, not how long you get stamped in for. You earlier said you went to Singapore to come back for another visa exempt entry. Now you are saying you bought a visa, and now you are saying you are back in Phuket. At least get the details of your story straight...lolol. Earlier you also said you hadn't exceeded what you thought was the 180 day limit by 7 days. Now you say they told you you were over by 14 days, yet now you are back in Phuket. You are what is called a drama queen. The more you talk the more BS comes out. Oh, and your girlfriend is Laotian, and has no reference to what she can do entering Thailand, and what you can do. Now explain how you got back in Phuket. This I want to hear...lolol.
you do understand that immigration stereotypes and profiles, and you fit one of their stereotypes, so they refused you entry, and because you flew in they deported you, and it should have been at your expense. The immigration officer simply told you that, instead of saying the real reason which was they didn't want you, or any of those with you, in Thailand anymore. If you were getting to the 180 day mark on using visa exempt, that means you received an entry, and an extension twice already, showing them you were not a tourist, and simply trying to stay long term on tourist exempt entries, which they do not like at all. Neighboring countries come under different stereotypes, and are treated differently. Welcome to real Thailand, and how adept they are at identifying tourist entry abusers. immigration isn't stupid, as you expected them to be.
There are no scam doctors doing it. You actually have to have a documented medical condition that requires treatment over a period of time, and a letter from the doctor/hospital certifying the treatment plan, and the condition requiring treatment
