A tourist visa, also known as a visitor visa or travel visa, is a type of short-term visa that allows individuals to visit a foreign country for leisure, tourism, or recreational purposes. Tourist visas are typically granted for a specific duration, and they are intended for people who wish to explore and experience the culture, attractions, and natural beauty of the host country. Here are some key features and purposes of tourist visas:

1. Leisure and Tourism: Tourist visas are primarily designed for individuals who want to travel to a foreign country for recreational activities, such as sightseeing, visiting landmarks, enjoying local cuisine, and experiencing the local culture.

2. Short-Term Stay: Tourist visas are usually valid for a short period, typically ranging from a few days to several months. The duration can vary depending on the host country's policies and the individual's nationality.

3. Travel Purposes: They are typically for vacation, but they can also cover other leisure activities like attending special events, weddings, family reunions, or simply relaxing in a different environment.

4. No Employment: Tourist visas generally prohibit the holder from engaging in any form of employment, business activities, or paid work in the host country.

5. Tourism Industry Support: Tourist visas are vital for the tourism industry, as they promote international tourism, contribute to the local economy, and support the hospitality and travel sectors.

6. Eligibility: Eligibility for a tourist visa may depend on factors such as the applicant's country of citizenship, travel history, financial means to support their stay, and the absence of any security concerns.

7. Visa Categories: Some countries may have specific visa categories for tourists, including single-entry or multiple-entry visas, and different categories for short-term and long-term tourists.

8. Visa Exemptions: Some countries have visa exemptions or visa waiver programs in place for travelers from specific countries, allowing them to enter for tourism without obtaining a tourist visa in advance.

9. Conditions: Tourist visa holders are often expected to adhere to certain conditions, including having a return ticket, showing proof of accommodation, having travel insurance, and not overstaying the visa's validity.

10. Visa Extensions: In some cases, it's possible to extend a tourist visa if the traveler wishes to prolong their stay, but this is subject to specific rules and regulations.

NOTE: It's important to note that while tourist visas are relatively straightforward compared to other visa types, the specific requirements and processing times can vary widely from one country to another. Travelers should ensure that they understand and adhere to the visa's conditions to avoid any potential legal issues during their stay.
