Rio Grande Valley · Cameron County
Private investigator in Brownsville, Texas
250+ five-star Google reviews
Brownsville is Cameron County’s seat and a border city with its own courts, port, and family docket. J.I.S covers Brownsville separately from McAllen because the county, the last-knowns, and the drive are not the same.
We take Texas-side locates and process serving, family-law documentation for Cameron County, and insurance or civil support when the Texas nexus is real. Port and logistics employment show up in workers’ compensation and activity-check files.
If the work leaves Texas, we say so. Spanish-speaking clients use the same statewide number. You complete the assessment; a licensed J.I.S investigator is assigned. This is not a directory of Valley agencies.
