I'd like to study russian during 3 to 6 weeks in Moscow, Kiev* or in any other city where people speak russian (the two I mentioned may just be the most attractive in my point of view).
I'm looking for a very intense program (20 hours of study a week is a minimum) in small groups (10 people seems to be more than enough) that would include accomodation and visa support.

I already have some ideas but I'm looking for more in order to compare.

Thanks in advance for all answers
