This is a no-brainer, a sovereign nation must know the number of non-citizens in their country in order to properly manage immigration policy. For too long Democrats and businesses have subordinated the individual rights of our citizens to the benefit of illegal non-citizens. People who want to immigrate to our country must come here through the legal process and prove that they are coming here to contribute to our nation and not be a drain on us hard working law-abiding citizens. Anything else is unsustainable. Build the wall!
