I know of one more person who got an invitation.
Too many red flags. Guys, don't fall for this. It would not surprise me if the guy of Skies Aviation is behind it or so.
If you feel the need to do P2F, then go for EagleJet or Baltic Aviation Academy. At least there you know that you get what you pay for. It is unethical, but as said, you do not get screwed.
The fact that so many here have the invitation looks pretty much like luring.
Don't waste time and above all money on traveling there.
