Customs protection officers work at airports and seaports, monitoring passengers' luggage for smuggled items and collecting customs fees. They work closely with police and other security agencies and are sometimes required to go to court and contribute to resolving court cases related to customs violations.
As a customs protection officer, you will search travelers' luggage, vehicles, and even their clothes. You will verify if their documents are valid and question people who have been found carrying illegal items. You might have to arrest people or press charges against them, if necessary.
It will be your job to prepare reports on your findings and write up witness statements for cases that go to court. You might specialize in dog handling, undercover work, or perform surveillance duties, which all require specific training.
