DNA testing more common for immigrants coming into U.S.

U.S. immigration officials are increasingly relying on DNA testing for immigrants who are trying to bring in family members into the U.S. DNA testing is usually done as a last resort and is used in a very small fraction of immigrant petitions yearly. Nonetheless, a few politicians have called for an expanded use of DNA testing, such as New York City mayor Michael Bloomberg’s idea to create a national DNA or fingerprint database for all U.S. workers.
