The “T Visa,” which offers trafficking victims protection – and even  citizenship – in exchange for their help putting traffickers behind bars is an underused program, NBC reporter Azriel James Relph writes.  Since T Visas became available in 2002, the U.S. Bureau of Citizenship and Immigration Services has been authorized to issue up to 5,000 a year — or enough for 10 percent of the 50,000 men, women and children trafficked into the U.S. for prostitution and forced labor each year, according to the U.S. Department of Justice.
