They used to get the jury list from the voter roles, now they get them from the DMV.It applies to every one who registers to vote. That's where the federal government gets their jury list from. And if an illegal registers to vote, at some point they can expect to get a federal jury duty notice, which if they don't respond to, can result in fines and jail time.
And i'm sure when they're hauling them into court, somebody would discover their illegal status, adding to their problems astronomically.
