You mean you don't have one? Poor, poor you. The first thing you need to acquire one is a birth certificate from an EU nation (mine is British). I keep my EU passport right next to my Canadian passport. It is soooooo much easier to travel in Europe and in Commonwealth countries having that pretty maroon booklet.
Yeah, I got 2 passports as well.. Canadian passport and 1from that gun-toting nation just south of the line. Live 17 years of my life in Texas and 2 years in California.. they rest mostly in Canada.
I got my citizenship when I was married to a US citizen.
