I don't think it's "PC and ridiculous" so much as it's self-serving censorship. Tech employer types who frequent this board are generally pro-visa while the rest of the country is suspicious of it. Some are suspicious for xenophobic reasons, others for economic ones.

And before anyone accuses me of xenophobia, I think if we need their skills we should give them citizenship so they have the same rights, same mobility, and same negotiating power as the rest of us. If they don't have that parity, it lowers the bar for the entire market (citizen and resident alien).
