Getting citizenship at birth does not really count in my book. However putting efforts to get one - does.

Friend of mine has five. He was born in Ukraine, back in times of Soviet Union, but starting from student years lived in Russia. So he got russian citizenship. Then he moved to Israel in beginning of 90s and after some time got citizenship there too. After that applied and got approved for Canada, moved to Vancouver, stayed and got canadian citizenship. In mid-2000s relocated to California on H1 and after seven years got green card and citizenship. And just couple of month ago he reinstated his Ukrainian citizenship.
