Then EU citizens should support undocumented immigrants, as we do in the US. It is inhumane not to give them full welfare.

Is your first sentence sarcasm or you don't see news?

Sadly I would consider now that America's just not an ideal position for immigration right now and this will remain a scar for America imo.

Many of people I know (or friends of friends/brothers) are migrating from America to either Europe or shifting back to India.

I don't think that America can particularly do something about it. Trust's pretty fragile.
