Customs and Border Protection
CBP's primary aim is to prevent terrorism. CBP agents are at La Crosse Regional Airport to enforce agriculture, immigration laws, and customs. All the passengers are obligated to pass through CBP security procedures before crossing the border. CBP representatives are allowed to ask travelers all kinds of questions. Mostly these questions are regarding the purpose of visit/stay. It is necessary to cooperate with CBP agents by answering all the questions truthfully and honestly.
