Visitors' visas for holiday purposes do not allow engagement in business activities. If the purpose of your planned travel is recreational in nature, including tourism, amusement, visits with friends or relatives, rest, medical treatment, and activities of a fraternal, social, or service nature, then a visitor visa would be the appropriate type of visa for your travel.
A visitor visa is an indication that a person is authorized to enter the country which "issued" the visa, subject to permission of an immigration official at the time of actual entry. The authorization may be a document, but more commonly it is a stamp endorsed in the applicant's passport. Some countries do not require a visa in some situations, such as a result of reciprocal treaty arrangements. The country issuing the visa typically attaches various conditions to the visa, such as the time that the visa is valid, the period that the person may stay in the country, whether the visa is valid for more than one visit, etc.
