Article I, Section 8, Clause 4:
[The Congress shall have Power . . . ] To establish an uniform Rule of Naturalization, and uniform Laws on the subject of Bankruptcies throughout the United States; . . .
Despite Congress’s broad power over denaturalization, the Supreme Court has recognized certain limitations to this power, particularly with respect to the evidentiary requirements to sustain a person’s denaturalization such as the burden of proving that citizenship was unlawfully obtained, and the standard that governs whether a person seeking citizenship concealed a material fact relating to his or her eligibility for citizenship.1 In imposing these limitations, the Court has recognized the “value and importance” of citizenship, and declared that the consequences of denaturalization are “more serious than a taking of one’s property, or the imposition of a fine or other penalty.” 2 Thus, according to the Court, “such a right once conferred should not be taken away without the clearest sort of justification and proof.” 3
