Every Town A Border Town Act This bill requires the Department of State to designate Mara Salvatrucha (MS-13) and any successor organization as a foreign terrorist organization. Among other things, the designation allows the Department of the Treasury to require financial institutions to block transactions involving the organization. Additionally, an alien who is a member, officer, official, representative, or spokesman of MS-13 is considered to have engaged in terrorist activity and is inadmissible for entry into the United States.
