Hey, after complaining here I suddenly got mail. Maybe I should have complained earlier...
But please, was it like this in past as well: I have to pay for my travel to screening in advance (ticket, hotel, I don't know, everything) and I will get money back only after positive screening?? That's strange... and expensive. Ooookaaaay.
Does VAC give any documents about tax payment over there? I will need it here. Anyway it was not so sure for me after reading the standard contract version if tax is already paid with the salary or not. I asked the agency again, I will see what they say. Before I was sure payment would be after tax. Now I am not.
