No matter what you and I think, most folks go along with the idea that Fed's have more powers than those specifically enumerated in Article 1. The word 'immigration' does not appear anywhere in the constitution, yet we go along with the idea that the power to set limits on immigration is an inherent power of congress for the president to enforce. There are a lot of other things that you and I would take for granted that are like that.
mho is that we need to use some judgment here case by case.
Not sure what you mean:
Article. I. Section. 8.
The Congress shall have Power ... To establish an uniform Rule of Naturalization, ...
Section. 9.
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.
