If someone you know is detained by U.S. Immigration and Customs Enforcement, it can be incredibly challenging to find and communicate with them.

For example, it can take several days just to confirm where they are. Even after locating a loved one, it is possible to lose track of them again, as ICE regularly moves people between facilities without notice.

I’m a law professor at Temple University in Philadelphia, where I work with immigrant rights organizations on issues of ICE arrest and detention.
