OTM (Other Than Mexican)

The Border Patrol on the United States-Mexican border have called a (usually illegal) immigrant not from Mexico as an “OTM,” or “Other Than Mexican.” OTMs have usually been from Central America and South America, but in the 2000s, even Iraqis coming across the border were called “OTMs.”
   
“OTM” has been cited in print since at least 1977.

Mr. Walsh added that the increasing number of aliens flowing across the border were what the Border Patrol calls “OTM’s,” for “other than Mexican.” These tend to come from the “troubled triangle”—the countries of Nicaragua, Guatemala and El Salvador, all of which has undergone recent political upheaval—and generally enter the country with the aid of one of the burgeoning number of illicit organizations engaged in the criminal smuggling of aliens, he said.

For aliens known to the Border Patrol as “OTM,” or “other than Mexican,” the first contact with a smuggler usually comes in the homeland they are preparing to flee, and contacts are not difficult to make.
