Is it difficult to study in the United States, such as a visa exam?

There is no clear statement about the difficulty of studying in the United States, but there is one link that distinguishes it from other countries: applicants need to go to the embassy for an interview in person. Actually, the interview is not terrible. The visa officer will ask the applicant some questions he cares about, which usually won't take long, 2-3 minutes, so the interview is very important and directly affects the visa officer's final decision.

First, answer truthfully according to the information on the 160 form and the i-20 form.

Second, the sentences are fluent, clear and fluent.

With your comprehensive information, the interview is good, and the general problem is not big.
