Hence the solution is to start visiting the Schengen area for a purpose other than transit. Here's what your friend should do:

I'm a Russian citizen and US resident as well. My advice to you: always apply for a Schengen visa in Russia! I have had 1 and 2 years multi-entrance Schengen visas, and now I got a 5 years one!
