Do passports and Consular Reports of Birth Abroad constitute conclusive proof of U.S. citizenship such that the State Department’s revocation of these documents is not impermissibly retroactive? Sonya Chung (’17) and Zi Lin (’17) examine this question, based on their experience as writers of the problem for the New York University School of Law 2016 Immigration Law Competition. Their Contribution discusses the state of the law surrounding passports and CRBAs as evidence of citizenship and their revocability. The Contribution argues that courts should allow individuals to use these documents as conclusive proof of citizenship and that the State Department’s power to correct its own errors should be circumscribed carefully in cases where there has been extended reliance on citizenship rights.
