Gee. That might be a consideration, but the police where I work cant get them to stop stabbing each other long enough to ask them to fill out citizen papers.
HERE's A BETTER IDEA. Have them return to their country of origin and fill out the correct paperwork to begin with.
(By butting in line, they are in effect stomping on the face of all good and decent people who are trying to come here legally.
And make sure they are disease free, non criminals who really want to assimilate into American life instead of just taking advantage of our lenient legal system in order to get over.
