No affiliation or endorsement
Passumi is an independent study tool. It is not affiliated with, authorised by or endorsed by U.S. Customs and Border Protection, USPTO, SOCRA, ACRP, PRIM&R, the CSCA organisers or their testing providers. Exam names identify the subjects of preparation; their respective owners retain their trademarks.
Practice material and results
Passumi’s original questions are preparation material. They are not supplied or approved by exam organisers. A practice result does not guarantee admission, licensing, certification or a passing score. Results for a free portion measure only that portion. Timers, layouts and study tools help with practice and may differ from the examination system.
Historical CBLE material
CBLE papers labelled as released by CBP reproduce government-published examination material. Use the regulations and reference editions applicable to the original sitting. An answer accepted for that sitting may no longer reflect current law. Passumi’s explanations are separate editorial material and do not represent CBP’s views.
CSCA preparation
All CSCA questions offered by Passumi are original practice material. They are not produced, authorised or endorsed by the CSCA organisers. Subject names, language options and study layouts are provided for independent preparation.
Accuracy and professional advice
Content may contain mistakes or become outdated. We do not claim expert review or exam-body approval. Verify important points against the relevant source and check current exam requirements with the organiser. Study material is not legal, medical or other professional advice.
Reporting an issue
If you find a problem, contact us with the exam, paper and question number. Please do not send confidential examination material or information about other candidates.
