Bring our troops home from Iraq , to guard the border. When they catch an illegal immigrant crossing the border, hand them a canteen, rifle and some ammo and ship them to Iraq.
Remember, If they have children, do what the current procedure for military personnel calls for. Have them give up custody of their children to their family far, far away (if they have any) and give them substandard health care and lower than welfare or prison benefits.
Tell them if they want to come to America, they must serve a tour in the military (Man or Woman). Make sure that there is no way of them assuming that if they are to be deployed, that they can not claim to be a hardship case because they can't possibly spend time away from their obligations here (like so many National Guard volunteers have done).
Give them a soldier's pay while they're there and tax them on it
Plus, force them to give money (by monthly allotment) to various charities because it makes the unit they are serving in look good. The Officers above me didn't require it, but they would not make things go well for us if we didn't contribute. They did it to me for over a decade and a half. Paying for charities (which would give it away to people or causes that in my opinion were not worthy of the money. Especially, when my family was eligible for WIC, government assistance (which was impossible to get even though we qualified for, and possibly food stamps.
After their tour (and if they receive an honorable discharge from the service) they will be allowed to become a legal citizen since he or she defended this country. They will also be registered to be taxed and be a legal patriot.
Now this sounds like a good plan to me!
