Hi Ana this is a big question as visas for people to do business is one thing and setting up companies with the proper permissions and in this proper corporate format is entirely predicated upon the type of business you want to be in, what kind of investment you've got and whether you want to go with a BOI, a treaty of Amity or a Private limited company where you have minority shares in the company. I I'm a business advisor helping people set up the right type of company and permissions in Thailand. If you want to discuss in detail I'd be happy to get on a call with you

If you can get the if you can get the shop to issue a new invoice after your last entry date then it shouldn't be a problem

You might be able to. The rulers only Goods purchased within 60 days of your departure date and get a vat refund. Your problem is you have an accident entry that is after the purchase of the goods. Worth a try though, would love to hear if it works

There great care centres here in Chiang Mai. You can get a retirement visa. I suggest you contact

@Amanda *******

her company can help get your visa sorted. I'll send you a link to the care centre

That's all depends on the type of business you want to do here. Also on which passport you are using that has an effect on the type of Visa you can get. There are a lot of options and I would need to know more details before I can suggest anything. Send me message if you want to have some more details on what options you have. I run a business that helps people who are looking to start a business in Thailand.
