4: I am a F1 student. In this winter, I will come back to China. The first time, I applied for my visa in Guangzhou City, so this time, people in embassy said I had to renew it in Guangzhou again. They said I cannot renew visa in Beijing. But, my flight was from Chicago to Beijing. If I can renew visa in Beijing, that will be much better. I will stay in China for less than 2 weeks, I did not want to fly to Guangzhou for visa again.
Beijing NIV Unit: You can renew your F1 visa at U.S. Embassy in Beijing
