bit later but he added a note to my passport. If i not show up he said he will fine me 😂 Also depends if I leave before but he's pretty serious about it.
I think you need to proof the source of income coming from even when it's Fiver for example. Somehow I think u are registered in a way and thats something you can show.
im Dutch and business owner. I got it so easy with kvk proof. I can show u exactly how i did it and got mine in 5 days. Send me a pm if u like. Can share my outline and letter.
you have a business registration? You can ask 2-3 clients if its ok to share the agreement you have with them. Also emails between you and the clients showing they are your actual clients. Describe your business with them from A to Z with examples and proof. Add some paid invoices as well.
I have my own company (sole proprietorship) in my home country and we do have a DTA with Thailand yes. I also do not want everybody to know back here that I stay Thailand > 6 months because of some other stupid rules. So again, if I pay my tax here back home lets keep it this way, I don't mind, but double tax is ridiculous.
