Is it necessary to apply for face-to-face training for American individual tourist visas?

It's not necessary. Don't let the visa officer suspect that I have an immigrant during the interview, so that I won't be refused a visa.

Reasons for refusal of visa:

1. The visa officer suspects that I have an immigration tendency.

2. The only reason for the visa officer to refuse the visa No matter what background the student is, the visa officer first assumes that every applicant has an immigration tendency. The mistakes that must not be made in the visa process are: don't let the visa officer find any reasons for refusing the visa, such as not knowing parents' income and work place, not knowing the school's consumption, not knowing their savings, not knowing the information of American universities, not telling them what they studied or chose, and not telling them whether they are sensitive majors.

The visa officer is very interested in my financial situation. The visa officer will think that the applicant will stay in the United States to make money after studying abroad and will not return to China immediately. However, if the applicant has enough funds or his parents have a good career in China, the visa officer will think that it is easier for the applicant to succeed in his career after returning to China, so he must provide as many proof of funds as possible, such as stocks, funds, insurance, real estate, car production, antique photos and so on.
