LOS ANGELES (AP) - Bradley Waite wanted to bring his adult daughter to the United States from Jamaica but couldn't prove they were related - she was born out of wedlock, so his name was not on her original birth certificate. U.S. immigration officials did something that is unusual but becoming more common: They asked for DNA tests. Waite grumbled over the $1,000 cost as he submitted to the testing several weeks ago. "We needed more proof but I wish I didn't have to take it because it cost too much money," said the 52-year-old construction worker in New York City. Genetic tests are playing a larger role in the U.S. immigration process. In some cases, the government is asking for DNA proof of a family connection; in other cases, applicants are offering to be tested in hopes of speeding up a process that often takes years.
