I'm not an employee. I have a business license and am officially self-employed. So I only file my taxes once per year, instead of having it taken out of my monthly paycheck. The last paperwork was filed in March, and the next round won't be filed until next March. There's no other way to do it, as far as I am aware. But I'll be contacting a lawyer tomorrow to find out what my options are.
I suspect they are supposed to accept things like bank statements and invoices as proof of income, as long as it looks legit and everything has a stamp on it, but the woman I talked to last said she wouldn't accept it. You always get completely different information depending on who you're talking to.
The true root of the problem is that there are a lot of Vietnamese, Ukrainian, and African immigrants here, and the government doesn't want any more of them here. But they can't legally discriminate against only those particular groups of people, so instead they just make it as difficult as possible for anyone with non-EU citizenship to get a visa. Then they do ridiculous shit, like only considering your tax-free income when calculating if you have enough money. When I pay taxes, I get a 60% deduction as a business owner. The other 40% is low enough that I don't have to pay anything on it, but even if I did, the taxes would only be about 30% of that. But they completely ignore that 40%, and only look at the tax-free 60%. My monthly tax-free income last year was 400 kc lower than what they calculate my current monthly expenses to be (that's about $20), so they are rejecting my application. I now have to find a way to prove that I now earn far more money than that. Wheeeeeeee!
