I'm a German citizen living & working in Austria. My parents are non-eu. I want to practice my right and invite them to live with me in Austria according to the Freedom of Movement Act/EU. However once of the main requirement is that I need to prove that my parents are dependent on me. I read that one sufficient proof is regular (monthly) transfers to them. However there is one big problem:
Their home country (where they currently live as well) has no access to the international banking system due to international sanctions. So not a single bank or any money transfer system is allowed to send them money (i.e yes even Western Union doesn't send money there).
Because of this ban, I was always sending them money via friends. However, because this has always been done via friends who were traveling to their country, then I have no documents to prove that I was sending them money regularly.
So can someone tell me what other ways which are accepted which I can use to prove their dependency on me?
