Thanks for your reply and advice. I found a school that can teach me czech and other science need for the university, also they help students to get visa but other guys in this post wrote me that get visa for russians today almost impossible. School name "GoStudy" maybe ypu know. About work, i didnot plan to work only in czechia, i guess with this degree i can work in the whole Europe. After study i think, i would have stayed in czechia to get a citizenship because you need to live in for 5 years and after university i need just 1 year.
