You want amnesty for all of the millions of illegal aliens in the US? Fine, put your labor where your mouth is and volunteer for the Fence Corps, a project to build a secure fence system along the southern US border. Illegal aliens that register as laborers for one year of Fence Corps will be given amnesty upon successful completion of their year's contract. Once the fence is built there will still be volunteers needed for maintenance and guard duty.
While you're at it, amend the Constitution so that there is no longer automatic birthright citizenship except for parents of native US citizens. In other words, no one whose parents are illegal aliens are to be granted automatic US citizenship simply by the fact of being born in the US. No anchor babies, to put it bluntly.
