Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. The visa allows a foreign citizen, to travel to the United States port-of entry and request permission of the U.S. immigration inspector to enter the U.S.
The "visitor" visa is a nonimmigrant visa for persons desiring to enter the United States temporarily for business (B-1), for pleasure or medical treatment (B-2), or combination of both (B-1/B-2) purposes.
For example, if the purpose for your planned travel 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, then a business visitor visa (B-1) would be the appropriate type of visa for your travel.

Personal or Domestic Employees: Under immigration law, visitor visas are limited to the following circumstances, for personal or domestic employee purposes of travel to the U.S. A visitor (B-1) visa is appropriate when all eligibility requirements are met, for a personal or domestic employee who accompanies or follow to join: 1) A U.S. citizen employer having a permanent home or is stationed in a foreign country, who is visiting or is assigned to the United States temporarily; OR 2) A foreign citizen employer in the United States in B, E, F, H, I, J, L, M, O, P, or Q nonimmigrant visa status.
As examples, if the purpose of your planned 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. If you are going to the U.S. primarily for tourism, but want to take a short course of study which is recreational (and not for credit towards a degree), and the course is less than 18 hours per week, this is permitted on a visitor visa. As an example, if you are taking a vacation to the U.S., and during this vacation you would like to take a two-day cooking class for your enjoyment, and there is no credit earned, then this would be permitted on a visitor visa. A consular officer will determine the visa category you will need based on the purpose of your travel, and your supporting documentation.
