What is the difference between the B-1 business visitor visa and the B-2 tourist/pleasure visitor visa?

The B-1 and B-2 visas are grouped together as 'B' visitor visas, but they serve distinct purposes under U.S. immigration law. Both require the applicant to prove nonimmigrant intent—that they intend to depart the U.S. at the end of their authorized stay.

B-1 Visa (Business Visitor):

The B-1 visa is for temporary visits for legitimate business activities that do not involve employment or receiving remuneration from a U.S. source. Permitted activities include attending professional conferences, negotiating contracts, consulting with business associates, soliciting sales, or engaging in independent research. The key is that the primary source of funding for the trip and the purpose of the activity are foreign-based.

B-2 Visa (Tourism and Pleasure):

The B-2 visa is for tourism, vacation, visiting friends or relatives, medical treatment, participation in social events hosted by service organizations, or engaging in amateur contests or performances without receiving payment. It is fundamentally for leisure, recreation, or personal reasons.

Combined B-1/B-2 Visa:

In practice, most applicants apply for and receive a combined B-1/B-2 visa, which allows the holder to enter the U.S. for either business or pleasure, depending on the purpose of their specific trip. When entering the U.S., the Customs and Border Protection (CBP) officer at the port of entry determines the authorized period of stay and notes the purpose of entry (either B-1 or B-2) on the I-94 arrival record. It is crucial for the traveler to clearly state their purpose to the CBP officer upon arrival, as using B-2 status for B-1 activities (or vice versa) can lead to complications or status violations.
