Minor correction, I must object to the use 'immigrant' as it does not apply. They are illegal aliens, they have no inention of ever gaining US citizenship.
im⋅mi⋅grant /ˈɪmɪgrənt/ Pronunciation [im-i-gruhnt] –noun
1. a person who migrates to another country, usually for permanent residence.

These are not 'immigrants' as they are here only long enough to get enough money amassed to move home and live wealthy. They have no loyalty to this country, they do not embrace our culture, language or ethics. They have no desire to see our country propser, they are nothing more than a parasite. They consume, they take what they can get; then they leave, leaving a trail of crime, garbage and contempt all the way back across the border.
