The Department of Homeland Security on Monday announced a one-time increase of 15,000 additional visas for low-wage seasonal workers for the remainder of this fiscal year, a seeming about-face from President Trump's "Hire American" rhetoric, following heavy lobbying from fisheries, hospitality and other industries that rely on temporary foreign workers.

The increase represents a 45 percent bump from the number of H-2B visas normally issued for the second half of the fiscal year, said senior Homeland Security officials in a call with reporters.

The visas are for workers taking temporary jobs in the seafood, tourism, landscaping, construction and other seasonal industries - but not farm laborers...

See Donald Trump for how things like this were completely foreseeable.

If Trump were smart and patriotic, he'd take steps to help those industries that supposedly can't find enough workers, even with some form of a WPA. Such a program or subsidies of some kind would have to be handled carefully, and Trump only knows how to do things in the most lunkhead ways possible. If he hired or listened to smarter people, they could design a program that would get Americans working those jobs, rather than giving corrupt companies all the cheap foreign labor they want.
