If you are denied entry at a U.S. port of entry in 2026, you are typically detained by Customs and Border Protection (CBP) until you can be placed on a return flight. You do not have a "right" to a lawyer for administrative processing, but you can ask to speak with a supervisor. There are two primary outcomes: Withdrawal of Application, where you are allowed to leave voluntarily (this is the better option as it usually doesn't result in a long-term ban), or Expedited Removal, which is a formal deportation. An Expedited Removal order typically carries a 5-year ban on re-entering the U.S. and cancels any existing visas. Your electronic devices may be searched, and your biometric data will be recorded. Unless you express a credible "fear of return" to your home country (triggering an asylum interview), you will be held in a secure airport holding facility—not a jail, but not a hotel—until the airline that brought you is able to fly you back to your point of origin at their expense.
