Denver International Airport (DEN) is the third-busiest airport in the U.S. by land area and serves as a growing hub for international travel, with direct flights from Mexico, Canada, the UK, Germany, and other countries.
CBP officers at DEN screen thousands of foreign nationals per week, and immigration enforcement at DEN is increasingly common as global travel expands.
Whether you’re traveling on a visitor visa, student visa, work visa, or ESTA, entry is not guaranteed. A single interaction at the airport can result in deportation, visa cancellation, or even a multi-year bar from returning to the U.S.
