Many things (like this one) boil down to this: You can't have it both ways.
We either 'manage' (my word) influx of people who hate us and wish to do us harm, or we don't. Things take time to sort out. I have wonderful Filipino in-laws, and I'll be very sorry for them if some of this interferes with any of their travel plans, but they can't have it both ways. If their government supports terrorism in any way, the ones that got here legally, work hard, became US citizens, etc. are among the fortunate. The others will have to wait.
The VA used to hire nurses who held a Green Card, but that is no longer the case, for at least some 25 years. I don't know what influenced either decision (probably a nursing shortage at some point brought them in to work with the GC). If a non-US citizen wants to work as a nurse at the VA (at least my VA, he/she must become a naturalized citizen. As far as I know the ones who were already hired didn't lose their jobs, just new policy exempting those who did not.
Edited to add: Did you every punish the wrong kid based on what some other person told you? If you had more than one kid, I'd say you probably did. Did you ever lash out at a teacher who gave your kid a failing grade, before you found out your kid was skipping school? Just human stuff, but that's how it works. You (and our POTUS) did the best you could, what you thought was right, until you had time to sort things out. Life ain't perfect.
Anyone who harbors hate for an ethnic group across the board, e.g. Muslims, I don't support that of course. But when one belongs to an group where a majority or the leadership or whatever hates the US and intends to harm us, I'm sorry but they are bound by whatever restrictions are put into place at a particular time.
The internment camps during WWII, a look back at that enrages a lot of people NOW. But THEN, without the intelligence mechanisms we have today (and I'm not so sure about that either), what was done was done to protect your moms and dads and grandparents, all US citizens, even if it was overdone. I'm sorry, but we have the advantage of looking back at it today.
I have Filipino in-laws, the best people you could possibly know. Decades ago they paid their dues, filled out the papers, waited years, finally approved to come to the US, got jobs, became naturalized US citizens (a huge family, BTW, and my brother married one, a nurse). They still have family over there. If any of their travel plans are impacted right now I am very sorry for that, but that's the way things are. And if their leaders support terrorist actions, again I'm sorry if this causes any of my dear SIL's relatives problems, but that's the way things are.
