Line-level immigration officers have virtually unreviewable discretion to deny noncitizens the ability to enter the United States. This power extends not only to those who enter without inspection or arrive with counterfeit documents, but also to those who travel to the United States with the U.S. government’s express permission—i.e., visa holders. These noncitizens can unwittingly be caught up in the expedited removal process, which affords only minimal procedural safeguards and heavily circumscribes judicial review of officers’ actions. This Note argues that, despite these limitations, federal habeas courts should take advantage of their ability under the statute to inquire into whether an expedited removal order in fact was issued. In particular, courts should insist upon compliance with critical procedures required by the agency’s own regulations, without which an expedited removal order may be said not to exist at all. Informed by fundamental principles of administrative law, such an insistence on procedural compliance could help correct some of the worst abuses of the system notwithstanding the lack of constitutional due process protections for arriving noncitizens.
