Two Vietnamese cousins are being sought for allegedly lying to authorities about being victims of human trafficking.

New Jersey's attorney general's office announced arrest warrants Thursday for Long Ngoc Nguyen and Ngoc Hong Doan. The 23-year-olds are believed to be living in Minnesota.

They are each charged with two counts of false incrimination, which carry maximum prison sentences of 18 months.

Authorities say the two came to the U.S. on student visas in 2007 and then claimed the Pennington couple that housed them forced them to work unpaid as domestic servants and in nail salons.

They allegedly admitted they were lying in May after they'd relocated to Minnesota and were scheduled to give grand jury testimony.

Authorities say the couple was seeking special visas offered to victims of human trafficking.
