Public school and illegals

I am still trying to figure out how the illegals are able to register their kids in our schools.  For citizens, you need a birth certificate, shot record, and proof of residence.  Do we just waive all that if someone is illegal?  Maybe I need to borrow a kid and register him or her for school so I can find out how they get around the rules that citizens have to follow.  Congress writes these rules.  They also write the rules for medicaid and food stamps and never kid yourselves, illegals get both.  Maybe Congress can identify with them because all of Congress is on welfare.  They are taking money from the taxpayer for a job they don't do.  They are also taking benefits. So I guess they do identify with the illegals.  Sure seems like it to me.
