Something needs to be done to deal with the US children of immigrants. I don't think it's right to make them leave with the parents who are here without documentation. This is a great hardship for the children and families. Most of the non-documented are working in lower paying jobs and don't seem to have money for passports for the children if they have to leave.
Why the contribution is important
We are investing lots of money in their education. It would be worth it to keep them here and get them into the workforce without sending them to inferior education in their parents' land of origin.
