The single woman from Beijing said she was recently refused a visa and told to re-apply when her personal life and finances were more stable. "I'll go anywhere but the U.S. now," she said. "I thought America was supposed to be a country of freedom." To visit the US, Chinese nationals must prove that they have enough money and family or business ties that make it likely they'll return to China. The Department of Homeland Security said it did not keep records on how many Chinese overstay their visas. Student visas can be refused on grounds of national security. Beijing native Tan Ge, 25, believes he was not accepted after he stated his interests in infrared technology and nanoelectronics on his application. He now studies in Canada...
