I didn't feel very nervous not only I have already had experience but also my status for visa is student.
However, I felf worried when I saw the meeting official staffs!
I interviewed with a America staff last time because there were three American in the meeting.
However, a annoying Taiwanese woman was there!
You know...she is very famous for failing people who want to get the visa.
She asked some question" why do you want to go to America?"in Chinese.
And if the person answer" I am going to study master degree in America."
She began changing form Chinese to English to ask questions.
And I saw some people even talked with her in English fluently, but they could't get the visa.
She often spent more than 10 mins to ask many questions, and let them fail.
Fortunately, I met an American staff again.
And you know...he didn't ask any question as last time, and let me get the F1 visa.
He spent just 1 min.
