What is the DS-20 19 form in the US visa?

The DS20 19 form is the most prerequisite for you to go to America. Before this form is available, you should fill in DS156157158. Before the visa interview, all applicants must fill in the DS- 156 electronic visa application form. All applicants aged 16 also need to fill out the visa application form of DS- 157. In addition, all applicants for F (student), J (exchange visiting scholar), M (vocational and technical training student) visas and family visa applicants (F-2, J-2, M-2) must also fill in the DS- 158 visa application form, which is meaningless.

DS20 19 is a form issued by the company you want to apply for, which contains your personal information and their consent permission, as well as the information of the company where you study or work in the United States, and your SEVIS number will be on it. Its function is to tell the visa officer, "My company wants you, and I have passed your application here", which is equivalent to you being "invited". Then the visa officer will know where you are going to the United States, what you are doing and how long you will stay, and then consider other personal information you want to verify next.

Sevis is a system for storing information of students and visiting scholars. The system is used to store accurate and current information of non-immigrant students (with F and M visas), exchange visiting scholars (with J visas) and their families (with F-2, M-2 and J-2 visas), so that schools and project sponsors can send necessary information to the Department of Homeland Security and the State Council through the Internet during the whole stay of students and exchange visiting scholars in the United States, and send notices when the situation changes. Kind of equivalent to your identity information in the United States. After online payment, there will be an authentication information that belongs to you and will be registered in the US Department of Homeland Security. A Department of Homeland Security number will be generated for you online, similar to your foreigner ID number in the United States. This is also needed for visas!
