Can I apply for a retirement 'O' visa at age 55 if I'm leaving Thailand at the end of June?

Hi Nick, When applying online for your 60 day tourist visa did you have to show proof of an onward flight/travel from Thailand ?

You might be better off doing a visa run to Laos and getting another tourist visa to get your 90 days. You can even make a trip out of it and see another country. Much simpler if you have no plans of getting the retirement long term in Thailand.

You absolutely can, though it might be a bit tricky to time it correctly if you actually want to get the full "extra" 90 days. This is why:

You need to apply for the Non-O visa when you have 14-21 days left on your tourist visa extension (the amount of days varies by immigration office), because after you apply they will give you an "under consideration" stamp in your passport. That's the date your new non-O visa will actually begin once you receive it, so you are losing those days you have to apply early.

The other thing is you need to have the 800,000 Thai baht in a Thai bank account in your name only to apply for the non-O visa. Are you prepared to go through the trouble of opening a bank account (difficult on a tourist visa) and transfer that much money to Thailand, only to leave after 3 months and worry about trying to transfer it all out?
