The person will no longer be able to apply for a visa in neighboring countries such as Canada or Mexico. For most people, this consequence is not serious. However, for nationals of countries far distant from the United States, such as India, China or Russia, where the U.S. Consulates are badly overworked and backlogged, and where visa applications are subject to higher scrutiny than at other Consulates, this penalty may be quite serious. This is a place where a foreign national may gain entry to the United States, such as an international airport, or border-crossing between Canada or Mexico and the United States. This is also called permanent resident status.
Most nonimmigrant statuses are valid for less than seven years.
Visa A visa is a document issued by a U.S. consulate abroad to foreign nationals. It is comparable to a ticket, because it shows the status that the bearer wants to have when admitted to the United States but does not guarantee admission . Not everyone is required to obtain a visa before entering the United States. Canadians usually do not require nonimmigrant visas. Mexicans are also exempt in many circumstances.
