For a time, I worked on getting H1b visas for Filipino health workers, mainly physical therapists and nurses. I liked them a lot, and they were extremely grateful to their employers for getting them the chance to work here. Wonderful people, and I have long believed the U.S. “owes” it to the Philippines to allow virtually unrestricted immigration from there.
But parts of the Philippines are Islamic terrorist nests; nests that are as threatening to Christian Filipinos as they would be to Americans here.
Call me whatever you want, but I would (as with Syria) favor allowing virtually unrestricted immigration by Christian Filipinos and Filipinas. But I would not favor allowing it from the Islamist areas at all. There is also a historical justification for it. The U.S. fought a bitter war against the “Moros” (Muslims) in the Philippines, and they never forgot it even if we did.
And it is no constitutional violation to admit or refuse to admit immigrants on the basis of religion, political beliefs or anything of that nature.
