The B visa is typically called the "visitor's visa." It is for individuals who wish to visit the United States for a short duration. There are two types of B visas: B-1 (for business) and B-2 (for pleasure or medical treatment).
An individual would come to the U.S. on a B-1 visa if his purpose is to consult with business associates, travel for a scientific, educational, professional or business convention, or conference on specific dates, settle an estate, or negotiate a contract.
If the purpose of visitor's travel is recreational in nature, including tourism, amusement, visits with friends or relatives, rest, medical treatment, activities of a fraternal, social, or service nature, and participation by amateurs, who will receive no remuneration, in musical, sports and similar events or contests, then a visitor visa (B-2) would be the appropriate type of visa for your travel.
People who come to the U.S. for a different purpose (i.e. to study, temporary workers, crewman, journalists, etc. must obtain a visa appropriate to their visit).
The presumption in the law is that every visitor visa applicant is an intending immigrant. Therefore, applicants for visitor visas must overcome this presumption by demonstrating that:
Once a visa stamp is obtained at the U.S. embassy or consulate, you would need to present yourself to a U.S. inspector at the port of entry such as the airport. The officer at the airport will interview you and determine the length of time to allow you to remain in the U.S. The length of stay is indicated on Form I-94 arrival/departure record, which is a white card that will be placed into the passport. Individuals are advised to carefully note the expiration date on this card.
A business visitor (B-1) will be granted a period of entry sufficient to conduct his or her business. Generally, these visits are approved for less than three months.
A non-business visitor (B-2) will automatically be granted a six-month period of entry. Only in unusual circumstances will a B-2 visa holder be granted a period of entry that is shorter or longer than six months.
Once in the U.S. a person may apply for an extension of his or her visitor's status. Extensions are granted for periods up to six months.
The program was established to eliminate unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Nationals of VWP countries must meet eligibility requirements to travel without a visa on VWP, and therefore, some travelers from VWP countries are not eligible to use the program. VWP travelers are required to have a valid authorization through the Electronic System for Travel Authorization (ESTA) prior to travel, are screened at the port of entry into the United States, and are enrolled in the Department of Homeland Security's US visit program.
