I sympathize with people like GeneralVeers, who go through the trouble of becoming a legal US citizen, because if anyone can run/swim across the border and if it doesn't make much difference once they are here...what is the point of jumping through hoops??
As a country, the US has 2 immigration problems that it doesn't want to deal with at this (or any) time. First is the ability to enter the country illegally, too many people can slip across the border and move in unchecked. The second is what to do with the illegal immigrants living here, some have lived here for many years.
Unfortunately, this is an unpopular political place, because most political leaders only care about the number of supporters, and there are huge amounts of voting Mexican-Americans who are fierce supporters of the illegal immigrants. This is similar to the slavery issue before the civil war, no president could get a majority by taking a side, and when a strong-willed president came to office, the south left...I am way off topic here, so I'll end this rant...
BTW, I'm all for treating anyone in need of treatment, and though not being able to communicate can slow things down, I'd really rather not have to deal with the consequences of not treating the illegal immigrants.
