I have an online friend from Armenia who wishes to visit Czech Republic (and generally travel, but Prague is his first choice). I did some research and it would seems that:

1. I have to sign an invitation for him
2. He has to prove he has enough money to be there and to travel back (I would not take the responsibility)
3. I should take care of housing

Now I have absolutely no experience with that. He claims to have no problem with money, offered to send papers to prove that, even some money ahead to me. But I am a very careful person and would like to ask if anybody has experience with that and what should I keep my eyes on etc. Which brings me to more questions: 4) How much responsibility over him would I have? 5) Insurances - those are managed on which side? 6) He wishes to travel around the country and I won't be able to go with him.

TLDR; Online friend wishes to visit my country in EU and I have no experience with that. Please share your experience and some material to read.

Thank you.
