Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for a temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (visa category B-1), for tourism (visa category B-2), or for a combination of both purposes (B-1/B-2)

Business (B-1)

• Consult with business associates
• Attend a scientific, educational, professional, or business convention or conference
• Settle an estate
• Negotiate a contract

Tourism (B-2)

• Tourism
• Vacation (holiday)
• Visit with friends or relatives
• Medical treatment
• Participation in social events hosted by fraternal, social, or service organizations
• Participation by amateurs in musical, sports, or similar events or contests, if not being paid for participating
• Enrollment in a short recreational course of study, not for credit toward a degree (for example, a two-day cooking class while on vacation)
