A streamlined legal immigration process would be good, IMO.
Now, seriously doubt that it is possible to stop all illegal immigration at the borders, but I think better border enforcement is part of dealing with this issue.
That, and clear-cut laws at federal, state, and local levels for discovering and dealing with illegal immigrants.
If theyíre paying their way, Iíd let them finish.
Itís more money into the college (and the economy, probably), and educated persons are always a positive wherever they exist in the world.
Meh, I dunno...
But I didnít expect better than this, so itís not really a surprise.
