Aida T. Silva, J.D.

Aida T Silva brings more than 25 years of experience with the Department of Homeland Security (DHS) and one of its predecessor agencies, the United States Customs Service (USCS). She began her federal and military career as an Intelligence Operations Specialist with the Puerto Rico Air National Guard, U.S. Air Force, where she briefed fighter pilots on daily missions, analyzed sensitive intelligence, and evaluated highly classified materials related to terrorism.

Silva served on active duty supporting counterdrug joint operations with the U.S. Customs Service before becoming a Special Agent with USCS and later DHS. She successfully investigated criminal and administrative misconduct within the legacy U.S. Customs Service and, following 9/11, played a key role in the transition of Internal Affairs from USCS to the newly formed Office of Professional Responsibility under Immigration and Customs Enforcement (ICE).

She became the first and only female Resident Agent in Charge for that office, supervising investigations involving personnel from Customs and Border Protection, Immigration and Customs Enforcement, and the Air/Marine Branch in Puerto Rico and the U.S. Virgin Islands. Later, as Director of the San Juan Field Intelligence Unit, she oversaw intelligence research specialists, special agents, and National Guard analysts conducting threat assessments, financial‑crime analysis, and intelligence reporting in priority Homeland Security Investigations (HSI) areas.

In Washington, D.C., Silva concluded her career as a National Program Manager, coordinating multi‑agency operations related to child exploitation, intellectual property rights, and nationwide undercover initiatives supporting the Victim Identification Program.
