Tancredo Wants Future Immigrants To Provide DNA

A Republican Presidential candidate says people seeking visas to join relatives in the U.S. should take DNA tests to prove their family ties. Colorado Congressman Tom Tancredo has introduced a bill requiring the DNA sampling. He says documents provided by immigrants are sometimes sketchy and unreliable.But Tancredo says the DNA tests would make sure applicants "are who they say they are" and "help protect the integrity" of the immigration system. Immigrants would pay for the DNA costs through visa application fees under the proposal.
