(I should clarify that I’m fully in favor of immigration programs that serve to increase the density of highly qualified individuals in the US and to fill positions which would otherwise go vacant. If as a small side-effect, those programs depress wages via increased supply, that’s still an excellent trade for the population. I am not in favor of visa programs substantially/primarily aimed at decreasing wages.)
That is why George W Bush and older generation Republicans always supported legal AND illegal immigration. Their constituents were the businesss that thrived and made more profits from a cheaper laborforce.
The Democrats were historically hostile to immigration because their base was the working class. Now that Wall Street and Big Business has gone Democratic since Bill Clinton and the New Democrats there will be more supply of labor and thus lower wages ceteris paribus.
Today I learned another useful latin expression.
It is called L-1 Intra-Company Transfer Visa: L-1A and L-1B for transfer of managers and specialists
