Carlos A. Roca-Roca, 35, was charged with theft by extortion and theft by deception, said Fairview Deputy Chief John Pierotti on Monday night.
According to Pierotti, police began investigating after Roca-Roca told the "family friend" in Bergen County that Roca-Roca knew someone who worked at the New Jersey Department of Motor Vehicles.
Roca-Roca told the victim that he was on a deportation list, and demanded $6,000 to have him removed, police say.
Roca-Roca threatened to have the victim deported if he didn't pay, police said.
Roca-Roca later admitted he made up the story to get money due to personal financial difficulties, police said.
The investigation was led by Detective Diego Porras.
