The Hill reported media reports in the South American country say consular officer Edy Zohar Rodrigues Duran has been pulled back to the United States.
The Washington publication said the scandal allegedly involves the sale of visas to the United States to suspected drug dealers and others.
"We are aware of the allegations of improprieties relating to a consular officer formerly assigned to Georgetown, Guyana," State Department Spokeswoman Jen Psaki told reporters in Washington. "This department takes all allegations of misconduct by employees seriously.
"We are reviewing the matter thoroughly. If the allegations are substantiated we will work with the relevant authorities to hold anyone involved accountable."
