Tourist, visiting, and temporary visas are types of non-immigrant visas that allow foreign nationals to enter the United States for a temporary period of time, typically for tourism, business, or medical treatment purposes.

Tourist visas are also known as B-2 visas, and they are issued to foreign nationals who wish to enter the United States for tourism, vacations, or visits with friends or relatives. These visas are typically valid for up to 6 months and may be extended in some cases.

Visiting visas, also known as B-1 visas, are issued to foreign nationals who need to enter the United States for business purposes, such as attending meetings or conferences, negotiating contracts, or conducting research. These visas are also typically valid for up to 6 months and may be extended in some cases.

Temporary visas, also known as H-1B, H-2B, and other similar visas, are issued to foreign nationals who have a specific job offer from a U.S. employer. These visas allow foreign nationals to work in the United States for a temporary period of time, typically up to 3 years.

To obtain a tourist, visiting, or temporary visa, the foreign national must submit an application to the U.S. embassy or consulate in their home country. The application process typically involves submitting personal information, including their travel plans, financial resources, and ties to their home country.

During the visa application process, the foreign national may be required to attend an interview with a consular officer, who will determine if they meet the eligibility requirements for the specific visa. The consular officer will evaluate the applicant's intention to enter the U.S. for a specific purpose, their financial resources, and their ties to their home country.

Once the foreign national enters the United States on a tourist, visiting, or temporary visa, they must comply with the terms and conditions of the visa. This includes adhering to the specific purpose of their visit, complying with immigration regulations, and leaving the United States before the expiration of their visa.
