I am planning to visit Russia for 2 Days. I know that I must register within 3 days of entry. Do I need to register at all if I am only in Russia for 2 days? (I am flying into KAZAN and out of KAZAN)from Istanbul. Thank you, Bernard

He has not 2 nationalities. Betwean Russia and Greek not signed agreement about 2 nationalities.

No, there is no any special low which can provide you with visa if you are not married with your fiance, even you have common children. You can come to Russia to marry and make permission for temporary residence without quotas for three years.
