Well, I use it e.g. for check in in a hotel without passport. But a bit more advantage for the yellow house book which you then have for sure. E.g. getting things (car, moped, internet) on your name. The biggest advantage I had was one and a half year ago, when I needed to stay 12 days in a university hospital for Covid. 2 people in the same room had to pay 4,500฿ a day (but where insured as a Tourist) and I had to pay nothing. So saved me 54,000฿. Really need it ? No, but sometimes nice to have.
Not sure if you mean physically or digital ? For digital,
If you have a bank in your home country and have an app from your Thai bank account, you can easy do it in parts with your Thai bank app. The costs will be a bit higher but 'hey', think you need it only one time I guess.
Maybe it's also wise to already look to the future. If you already have a Thai bank account, start transfering (as international transfer) a bit more than 40,000฿ (if legaly maried for Thailand) every month. Cannot look into y'r pocket ofcourse but hey, you need some Baht in Thailand anyway. If you have done this 12 months, after that, you also can ask for a year extension with no need for the 400,000฿ banked money. Then don't forget a re-entry permit if you want to leave and come back to Thailand within tis year extension. Good luck ! 🙏
. With the 60 day extension, you mean the '60 days visiting family extension' ? This because you can do this only once a year I thought ? Or is it indeed once per entry 🤷♂️
