Congressman John Linder's version is the same thing in English: “U.S. General Population Act.”
“The question of immigration will, in my opinion, become the defining issue of the next generation. Unfortunately, the debate over securing our borders and protecting the interests of our citizens is too often demonized by the opposition and turned into an ugly accusation of racism. For this reason, I have introduced the U.S. General Population Act, a bill designed to align the immigration laws of the United States with those of Mexico. This bill simply reflects the same immigration restrictions implemented by Mexico with the same consequences for those in violation.” [Linder Introduces "U.S. General Population Act"] ”
