Test takers can download digital files of the following reference material at the links provided for use in their study. These links are provided for your convenience for study purposes but as the prescribed reference materials can change every year, it is recommended to check the official CBP site for the references prescribed for the exam that you propose to take. CBP will provide digital reference materials, with basic search functions, on exam day. However, it may be time consuming and difficult to download and view large electronic reference files on a single monitor. CBP recommends that examinees bring and use their own paper reference materials for the exam as a backup.
