R’s are pro-H1B because they want cheap skilled labor (engineers).
D’s are pro-H1B because they want more immigrants.
Either way, I no longer encourage my children to pursue engineering. And that is quite sad.
MS Google and Amazon all support more H1B for the stated reason that they bring expertise that expands their buisnesses, hence increasing sales and profits.
What they don’t state is that they prefer to acquire young talent, cheaply, and grow that talent within their own corporate cultures.
