Have a partnership for business, and both apply as the same. But 500k each. Any other way you will have issues I think. Don’t do “soft” for your partner if not legally married as you will struggle in the future.
If you use multiple accounts they still have to be in YOUR name only and submitted as a single document, so create a PDF with a cover letter to give explanation as to why more to an one account.
Make sure you apply at the embassy for your area or it will be rejected. And you can’t actually apply in Thailand so would have to leave to a neighbouring country to apply anyways
I use to pay electric as well as many shops. Have also used to pay rent as well to my landlord. But we do direct transfer from my other half’s bank account normally.
Any communication with them should be in writing. If you have receipt that details including lessons and they fail to provide then simply ask them for refund or will take legal action and sue.
But get them to admit it doesn’t include lessons before you do that. They don’t want bad publicity. They “lose face” and it reflects badly on them. But do NOT post the name publicly as they could sue for defamation if they lose money as a result of what you write.
Anonymous participant the abuse is in the use of tourist visas to stay long term for the period of time you stayed. It’s just how some immigration officers see what is technically illegal. I mean if someone came to your country and abused the system wouldn’t you feel a little off about it?
Also, consider that you just posted you volunteer in Thailand, if you actually have any understanding of how visas work, here that is considered “work” and is actually not allowed. Unlikely anything would happen. But I wouldn’t be posting about voluntary work at all.
