I'm living in Hungary with a (non-permanent) residency permit (Tartózkodási engedély). I want a relative of mine to visit me and stay at my place. On the consulate web site it says that I need to send a "letter of invitation". I don't know, what that letter should be like; I've never done it before. I did some research online, and my findings are contradictory; some say, I can write in English and just have to notarize it; others say, I should write in Hungarian and attach my work contract, my lease contract, and some confirmation from my landlord that this place is really his. Can you help me with that? Maybe someone had a similar experience?
