GPX/GXP USA (GPX), a  seismic surveying company based in Sealy, Texas, recently pleaded guilty to harboring and  transporting illegal aliens in U.S. District Court, Middle District of Pennsylvania.  GPX has  agreed to forfeit $250,000 cash and pay a $25,000 fine.
The field operations supervisor also pled guilty to a misdemeanor charge of aiding the  improper entry of undocumented workers into the U.S. He faces six months in prison and a  $5,000 fine.


The investigation by Immigration & Customs Enforcement's Homeland Security Investigations  (HSI), with assistance  from the FBI and Williamsport Police, revealed that in May 2011,  GPX and its manager hired 19 undocumented workers to work on a seismic surveying project in  Lycoming County, Pennsylvania without verifying the immigration status of the workers or preparing the required  Form I-9 concerning the workers' authorization to work in the U.S.
Thereafter, GPX falsely executed a contractor  compliance agreement certifying that all individuals were authorized to work  legally in the U.S.
