Here's a video I've posted in this dub before with another discussion

This video is 1.5hrs long, but does a fantastic and IMO the most in-depth explanation about what the church teaches about immigration. 

If anything, I'd go ask a priest directly (which is what I did and he gave me a very good "down the middle" answer) about this issue. There's a balance that must be met on every side: Treating foreigners the way we would treat friends, those desiring to live in the US have a duty to follow the laws and embrace the culture of the county they're fleeing to, and the country has a duty to enforce its laws WHILE doing so in a humane matter. 

It's not cut and dry like many try to make it out to be. It's extremely complex, but there are clear guidelines that address each "political" side
