I don't drink Chang or Leo, nor do I sit on a bar stool. I will not reveal my sources. I will edit my comment above and remove " I know for sure " and stick to my later comment of "strong chance of where this heading".
Let's revisit this in 18 months, and once the dust settles, I'll bet a box of Leo thst the TIN and long term visa will be linked.
Not right now, but I hear it in good faith that the long term goal will be to have all long term visa renewals linked to your tax status/return, if exceeding the 180 days. I.e present your tax information when renewing. Not trying to scaremonger, just highlighting the strong chance of where this is heading (eventually).
Congrats. Is the company registration certificate specifically requested ? I work for a US based multi national company and have a letter from my HR confirming my remote work , salary etc..... i'll have payslips, Singapore bank statements etc....
With ref to the proof of income. What country are you from ? My understanding is that you needed a stamp from your embassy and that the UK embassy ( for example) had stopped verifying that ? Or this is based on you earning inside Thailand ?
I got one today when leaving and didn't even realise I was able to, as I was leaving on an expired multi entry NON IMM O visa. The immigration lady pointed it out to me. Good friendly service.
