Yeah, I understand now. They have to offer that for whatever languange the country you have roots in speak. It's by law. You dont have to be an immigrant per se either, just have a parent or relative from another country (dont really know where they draw the line). So most people with parents from another country will take those classes instead of the regular french / spanish / italian classes or you can choose to take them both and remove another class from your schedule.
Its like this from kindergarden all the way through high school. Lol, in high school I actually went to my school and said I was from Kenya and wanted the english as a native language class

they didnt even bother to look it up since I was black. good times, but its actually a cool system because its important for people with parents who immigrated to be able to speak their native language. It helps learning and its important to be able to communicate with relatives when you visit the country you're originally from etc.
