Blind Chinese dissident Chen Guangcheng has arrived in the United States on a flight from Beijing, a month after escaping house arrest in China.
Chen, accompanied by his wife and two children, arrived at Newark Liberty International Airport, outside New York City, on Saturday evening local time.
Mr Chen had been hurriedly taken from a Chinese hospital hours earlier and put on a plane after authorities told him to prepare to leave.
One of China's best-known activists, Mr Chen won plaudits for investigating forced sterilisations and late-term abortions under China's "one-child" policy, but endured seven years of prison and house arrest.
He escaped from his village in April and was given sanctuary inside the US embassy in Beijing, triggering a diplomatic incident.
Officials struck a deal that let Mr Chen walk free, but he had second thoughts. That forced new negotiations that led to an agreement to send him to the US to study law at New York University.
