Nor does Article 1, Section 9, give the Feds Authority over Immigration

  If that part of the Constitution that enumerates the powers of Congress doesn't give the federal government power to dictate immigration policies, then how about the very next paragraph?
   That would be Article 1, Section 9, Paragraph 1. "The Migration or Importation of such Persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the Year one thousand eight hundred and eight, but a Tax or duty may be imposed on such Importation, not exceeding ten dollars for each person."
   This is clearly not referring to the general immigrant. It is referring to the importation of slaves. It gives Congress authority to end the importation of slaves beginning 1808.
   It uses the words "migration" and "importation" together, which indicates it is speaking of the slave trade. Slaves are "imported," not the general immigrant. Further, at the end, it says a tax or duty can be imposed on such importation. That is a tax or duty that was only imposed on slaves, not on everyone who came to America. So, it follows that this part of the Constitution is not referring to immigrants in general, only to slaves being imported.
