A blind Chinese activist who sparked a diplomatic crisis between Washington and Beijing last month filled out a Chinese passport application on Wednesday in his bid to study in the US. Paperwork for Chen Guangcheng, his wife, and two children was completed in a hospital, AP reports. The officials were sent by the government, the activist believes. Lawyers also tried on Wednesday to visit Chen\'s nephew, who was detained in Shandong province\'s Linyi city last month.
