How many visa and passport states are there in the United States?

American visa passport status can be divided into immigrant visa and non-immigrant visa.

American visa immigrants refer to those who intend to give up their original residence and nationality, enter the United States for permanent residence and apply to become American citizens. An immigrant visa is a visa for the purpose of immigrating to the United States. Generally, an application must be made to the US Immigration Service. After strict examination, the Immigration Bureau will issue "approval documents" to those who meet the requirements. Then, the applicant will apply for an immigrant visa to the American consulate abroad with this document. ? Immigrant visas can be divided into family visas, professional visas and special immigrant visas.

Non-immigrant visas are mainly "short-term" or "tourist visit" visas, and only temporary short-term stays in the United States are allowed, although "short-term" stays may last for several years. ? The categories of non-immigrant visas are mainly classified according to the main purpose of the applicant's visit to the United States. With a few exceptions, people who visit the United States with non-immigrant visas can only engage in matters related to their visa types in the United States.
