Roma-Los Saenz is a port of entry west of Mission
on US 83 and the Rio Grande, directly across from Ciudad Miguel Alemn, Tamaulipas, Mexico, in southwestern Starr County
. Roma and Los Saenz are actually two adjoining settlements that have incorporated jointly; Spanish is the primary language.
The population in Roma-Los Saenz has grown steadily from 2,154 in 1970 to 8,059 in 1990. Since 1979 a new water plant, a 500,000-gallon elevated water tank, a new fire and police building, and a new community center have been constructed.
By 1990 dry-land farming to the north, with 100,000 acres of irrigated river bottom around the city, provided a strong agricultural base.
