How can you find out who hires illegals?
We had an article posted a few weeks ago about Congress trying to find out that information.
Each year, the INS and SSA make reports regarding the Earnings Suspense File. The ESF lists undeliverable or unallocated W-2s; i.e., wage withholding statements that go to invalid SSNs - mostly illegals, sometimes folks who move with no forwarding address.
Congress looked into it, and found major corporations with thousands of employees whose records go to the ESF each year. They tried to get the names, and were told there was no legal obligation to disclose them.
Changing that part of the law might be a start toward answering your question...
I'm for militarizing the border, but I hire illegals. I live just outside of NYC and there's a group of maybe 50 that hang out at the same spot every single day for 15yrs. They live in the apartments across the street.
I help a lot of people with all kinds of tasks from taxes to moving, and when I need manpower there's only one place to go...and to be honest, I feel good helping them; these guys are amazingly hard workers.
