Visa workers aren’t allowed to vote at all, of course. However, once they get their green cards, and become citizens, H-1B immigrants vote Democrat.
The H1-B work-visa program is a mechanism by which American middle-class jobs are handed over to Asian immigrants. Sure, there are a few Canadians sprinkled in, but the H-1B program is overwhelmingly Asian dominated. And exit polls found that 87% of Asian-Americans voted for Hillary Clinton in the presidential election.
So, as President Trump drafts his executive order to change our cheap-labor importation policies, he should keep in mind the huge deficit in the popular vote that could derail his re-election campaign in 2020. These inflows of fresh Democrat voters need to damned-up, and ideally, reversed. There is a huge pool of former IT workers who have been displaced by Asian H-1Bs. If Trump gives them their jobs back, they will vote Republican for the rest of their lives.
Not only that, but most of these H-1Bs go to work for Trump’s enemies: Google, Facebook, Amazon, Apple, Microsoft, etc. Why would Trump want to boost the profitability of his enemies by providing them with cheap labor? They are just going to donate the extra profit to the Democrats.
