Travel / Non-EU citizens coming to Poland for 2 weeks. Do they need tourist invitations? [10]

Merged:

Poland's visit visa issue - is invitation mandatory?

To apply for a visit visa, is it mandatory to submit Official invitation (Zaproszenie) registered in Urząd Wojewódzki by the host in Poland, if the host is not having a permanent resident in Poland?

Is it possible to invite a relative if you are having temporary residence permit, but not working.
