welcome to the forum!
yes, visa requirements are pain. as a rule, Russia usually imposes biliteral visa requirements as tough as the other country. but i think it is possible to get Russian visa faster. thought it may cost more. ask russian embasy or consulate in Slovakia ( http://www.slovakia.mid.ru/
as for learning Russia, if you have any questions or need any help, ask away, im sure im not the only one who'll be glad to help. also, it may be better if you write in slovak, this way we learn or perfect or slovak too
or try writing in russian you'll learn faster
