The interview was conducted in Mandarin.

American visa interview content:

Usually, the consul will spend a few minutes talking with the applicants about their application for an American immigrant visa. In fact, face-to-face conversation with the consul is often a simple process, and the consul will conduct an interview in Mandarin. The consul will greet the applicant first and then start the interview.

During the interview, the consul will ask the applicant to take a fingerprint and take an oath. The most important thing to remember is that the applicant has taken an oath, so answer the questions truthfully. If you understand the question clearly, don't worry, you can ask the consul to repeat the question. Consuls should ensure that all applicants have the opportunity to answer questions comprehensively and honestly.

After the visa interview, the consul will tell the applicant whether the visa application is approved.

If approved, the consul will send a notice to the applicant, telling how and when to collect the visa package. After the interview, the consulate will keep the applicant's passport, print the visa and paste it on the passport.

If the application is rejected, the consul will explain to the applicant the reasons for rejection and what to do next. At the same time, the applicant will also receive a letter of explanation in both Chinese and English.

After the consul told me that the visa was approved or rejected, the visa interview was over.
