Got dismissed from jury duty yesterday

I got summoned a minimum of twice a year in the 10 years I lived in Lansing in spite of having gone in the first time with my Canadian birth certificate , It's a drivers licence lottery and I won it on a regular basis , my american wife got called once in the same period , she wanted to serve but got sent home after the first day of selection.

odd, I'm not for from Lansing (my wife used to study there) , ive lived in this area for 12 years now, and I've had a legal MI driverslicense all that time, but neither me or my wife (who is an American citizen) ever got invited
