Immigration reform is also about guest workers.
A foreign worker under the H2A temp ag worker visa will cost agribusiness a lot less than a domestic worker or an illegal masquerading as a domestic worker.
The problem is that the H2A has certain requirements that make it very difficult for agribusiness to use.
Advertising requirements
Negotiating a fixed date contract with the Labor Dept
The 50% rule
The three quarter rule
So if in the course of immigration reform, they reform the H2A ag worker visa to soften or eliminate these requirements it makes it better for those who want to hire these guest workers.
I understand the former being cheaper, but how is it with the latter? And how is that related to amnesty if it is merely a type of visa?
