Few?
There are roughly 66,000 low skill H-2B foreign employees in the USA at any given time.
And, Kirstjen Nielsen, Trump's Secretary of Homeland Security, requested a 15,000 worker increase for 2018.
Why can't Trump - and all the other employers who hire H-2Bs - just increase their wage scale high enough to attract reliable, hard working Americans?
If Trump can't afford to hire Americans, then he needs to develop a new business plan.
A lot of those are legal resident students, who only work part time, and that area is far more Hispanic than other areas. The news media plays on this information to make Trump and others look bad to the public! SAD!
H-2B workers are only hired in places, where Americans are not available or applying for the job.

Trump has explained this ad nauseum. He can’t get local workers. His jobs are temporary just for the season which is only several months.
