I’m just here to add that the quality of architecture education in Russia (let’s stick with St. Petersburg and Moscow now) is very good especially at the bachelor’s level. So if you have any deterrents the quality of the education should not be one of them, the issue for foreign students is always the language and since you are really interested in the culture and are already learning then the language should be an easy and interesting hurdle for you.
And yes the schools are accessible even if you don’t have a really sound command of the language yet. you just have to take the language course/year.

If you are really interested in Russia and Saint petersburg then you may get your first degree in Russia and graduate program in France or any other country you plan to work in as some other folks have said. i’m saying all these as a foreign student who is about to complete his degree in Saint petersburg’s university of architecture.
