Do you even read the constitution? Your lack of knowledge as a citizen is a disgrace. Try Article 1, Section 8. Eight would be right after seven, if you're stumped.
You do know the difference between Naturalization and Immigration, don't you?
"To establish a uniform Rule of Naturalization and uniform Laws on the subject of Bankruptcies throughout the United States."
That doesn't even come close to establishing that the federal government is empowered by the Constitution to have sole control of immigration. In fact, the word "immigration" isn't even mentioned in the section you cited.
I'm sure that you can find the federal legislation which claims this power for the federal government, but you claimed that it was in the Constitution. You would have made a better case by citing the Jurists' Amendment with its language on citizenship and naturalization.
Sorry, boy. You've run into someone who has not only read the document but who didn't even have to get out his copy to refute what you just claimed. Maybe you have read the Constitution, but you obviously disagree with its provisions.
