I'm going to apply for a visa at the American embassy soon. My visa is F 1, but I study languages. Can I speak Chinese when I get a visa? Or try to speak English?

Be sure to speak English as much as possible! No matter what you study, F 1 visa requires basic English communication skills, and speaking Chinese is very easy to be refused! He will ask simple questions, such as the name of your school, your city, your parents' jobs, what you took in the exam, and whether you have been abroad. Basically, you can answer it in a few words. Take it easy.
