If illegals are legalized that would be because of humanitarian reason not for anything else. All US governments has to do is pick up randomly here and there and start deporting them, this issue will go to the back burner. However, there could be exceptional cases like somebody who has lived here for twenty years and he knows nobody back home. In those cases, humanitarian case could apply. For undocumented ones, I haven't thought how to deal with them. However, for those who overstay visa there are thousands of easy ways to fix this problem. Here are few of my solutions for those overstaying visas. They might sound stupid but I think they works. 1. Have driver's license expire on visa expire date and don't issue another driver's license without renewal of visa. As soon as somebody's visa expires, his social security number can be cancelled. He can't own property, rent and do anything not even take the utilities. All of his identifications become illegal. 2. Amnesty can be given to those who leave the country voluntarily not by legalizing them here so that they can go to their home country and apply their visa. 3. One big notice can be brought that whoever stays here illegally will be left in an uninhabited island on their own if they don't return to their country. This may cause big controversy if that's a dead end for illegals but if the illegals living in islands want to go back home should be allowed to leave right from there. Right now, similar thing is done only for Guantanamo prisoners who have other convictions. 4. If it comes worse to worst! How difficult it is deport Mexicans to their border? Ninety percent of illegals problem will be solved right there. 5. For illegals from other country, offer incentives like one in number 2 above or something like there might be a chance that they can get visa back if they haven't committed any crime while staying here. 6. For legals on those with tourist and student visas, offer incentives like if they go back and wants to come back again their previous legal status should help for their credibility. It already does though. See how many ways can be imagined. I don't want to write anymore. It's just for the political reasons, the politicians want to address this issue separately.
