FILE - in this April 16, 2010 file photo, dissident writer Tran Khai Thanh Thuy is escorted from a court room in Hanoi, Vietnam. Thuy was released from prison Wednesday, June 22, 2011, and put on a flight to the United States, an official with the Ministry of Public Security said on condition of anonymity, citing policy. Thuy has been reunited with her daughter and arrived safely in San Francisco, said U.S. Rep. Loretta Sanchez of California, who has been advocating for the dissident's release since she was detained in 2009. (AP Photo/VNA, Thong Nhat, file)
