Immigration officials want victims of human trafficking to know there's hope for escape and a path to citizenship. Evelyn Sahli, head of the Portland's U.S. Citizenship and Immigration Services Office, says people who work with trafficking victims are receiving training on the T-Visa. The T-Visa allows victims to stay in the country with a work permit and apply for permanent citizenship after three years. Karen Fitzgerald also with Immigration Services says there are thousands of victims. Only 447 T-Visas were issued last year nationwide.
