Unauthorized immigrants face the most immediate danger due to the law but the Trump administration is hostile to legal immigration as well. They're seeking to decrease legal immigration and considerimg an executive order to deport legal immigrants for using welfare.

They are trying to ban by executive order legal immigration from arbitrary Muslim majority countries and all refugees (possibly temporarily but I expect them to try to extend it).

Steve Bannon sees the number of asian CEOs (which he greatly overestimates) as a bad thing.
