The Russian government agencies are willing to welcome outside foreigners - especially those of Christian faith - who wish to immigrate to Russia. There are support and network groups available to foreigners to help them with immigration and/or visa paperwork.
Sure...if you are Catholic, Poland is a good fit.
Does Serbians offer support and network groups for foreigners?
Why not? Nobody is interested in having LGBQT+, tranny, gender pronoun, equality, etc. shove down in one's throat.
Russia's winter is not for the weak. I live in the northeastern part of the U.S. that's similar to Russia's harsh winter conditions.
