Each type of visa serves a specific purpose and comes with its own set of regulations and requirements. In this article, we will explore some of the most common types of visas and the purposes they serve.

The tourist visa is one of the most familiar types. It’s designed for individuals who wish to visit a foreign country for leisure, sightseeing, and recreational activities. This visa typically does not permit any form of employment or business activities.
2. Business Visa
A business visa allows individuals to engage in business-related activities in a foreign country. This could include attending conferences, meetings, negotiations, or exploring potential business opportunities. It is important to note that a business visa usually doesn’t allow for direct employment within the host country.
