But I see that Russia is the most appropriate place for study because in my country many of them continue their studies there and don't seem to differentiate between culture and religion, because I see that those who study there are from my country from various ethnicities and religions. This is not because of discrimination, but we also need peace in terms of study and not having problems in the future.
It's going to be hard to judge who you fit into to a country from a far. If you really only want to study there and don't care about anything else it might work. But for spending a long time in a foreign county I would recommend to actually visit that country. Before I did my masters abroad I spend a long weekend of 5 days in that city. It's good to actually visit the university before and see how everything goes. It might be difficult though to travel right now with corona.
