it depends on your goal. I am living in Thailand now on nonO age 50+ retirement visa with one-year extension and multiple entry permit. Unlike the visa you had, I don’t have to keep leaving Thailand every 60 days (or 90 if I want to ask for extension)
Be sure to check out Krungthong Plaza. From what I can tell, if anyone asks where to go for bigger clothes in Bangkok, they will probably hear about this building.
Also more than likely, you will need to have separate accounts. Also if you are not married, it might be difficult to be beneficiaries on each other’s account is my guess. At my bank, I tried to list a cousin as my beneficiary and they were very confused so I am not sure how they will handle a partner.
