I'm in a dilemma. I'm an international student. My wife and I are accepted and will attend to a master's program in mathematics. The university is located in Moscow, Russia. The university has subject ranking among top 100.
Today, we have been informed of an option to study in a track program (2 years masters + 4 years PhD) which comes with an increased financial support. We were planning to apply for other high ranking PhD programs around the world. The difficulty is that we don't know if we can manage to get in the same PhD Mathematics program (or within the same city) after our master's. And we don't know if we will be able to adapt to Moscow or the university.
One thing we know for sure is that for now we both wish to study mathematics further.
What is your advice?
Should we commit for 6 years or struggle to find a different PhD program?
What can you say about doing graduate mathematics studies in Moscow?
