Most of these immigrants are Mexican 56% or Central American 22%. There is absolutely not reason why they ought to enjoy preference over anybody else. Let's make sure everybody coming in on a work visa speaks english and that no one group comprises more than 5% (English, Irish, Chinese, Indian, Poles, Estonians, etc.).
Ahh, but the English, Irish, Chinese, Indians, Poles, Estonians, etc. are not part of the coming United States of North America.
