First of all, as much as you like to call them undocumented, they are illegal. Regardless of age.

Not their fault, but the illegal actions of parents should not result in benefits to the child. Do you also agree mobsters, once found guilty, should keep their assets and funds so their children can spend their criminal proceeds?  Ridiculous.

Second, we already select and choose whom to bring in...it's called the immigration screening system. Look it up

Third, this is funny coming a from a 'professor' who lives under a protected system, yes, with borders to entry.
Try offering a teaching position to a private sector worker.  Nope, protected hiring system. 

Independent Senator? You mean Liberal, minority, senator.
