.....what can I have a more clear sentence on this question please I would be glad to help
ICE'S mission is to protect America from the cross-border crime and illegal immigration that threaten national security and public safety.
This mission is executed through the enforcement of more than 400 federal statutes and focuses on smart immigration enforcement, preventing terrorism and combating the illegal movement of people and goods.
If I see the document I'd be happy to answer your question:)
True and true
Hope that helps
