About International Services

Last Modified: February 24, 2024

Our International Services team acts globally to protect U.S. agriculture locally. With Foreign Service Officers and technical experts located around the world, we work to ensure the free flow of agricultural trade, help other countries enhance their animal and plant health infrastructures, and build and manage sustainable programs that keep harmful pests from spreading. Here’s a closer look at our work.


Our Trade Support Team helps keep export markets open by advocating on behalf of American agriculture. Based in the United States and abroad, our experts address plant and animal health trade barriers that could limit U.S. access to foreign markets. We build relationships with international counterparts and use scientific principles to assure them that our commodities are safe to import.

We work alongside the following APHIS operational programs and many other teams, organizations, and agencies involved in global trade
