Immigration Enforcement Transparency Act - Requires a law enforcement official enforcing an immigration law to collect specified data, including: (1) the basis for such enforcement action; (2) the individual's identifying characteristics, including race, gender, ethnicity, and age; (3) how long a stop or search lasted and whether consent was obtained; (4) a description of any items seized; (5) whether an arrest or detention was made, the justification for such arrest or detention, and the ultimate disposition of such arrest or detention; (6) the individual's immigration status and whether removal proceedings were subsequently initiated against that individual; and (7) whether the individual filed a complaint.

Requires the Secretary of Homeland Security (DHS) to compile such data and submit a related report to Congress annually.
