Business visas, cover work-related activities that can include:
- Consulting with business relations or colleagues
- Attending a meeting or education convention
- Contract negotiations or settlement of estates
- Engaging in business or industrial operations
- Attending corporate meetings
- Making acquisitions or purchases for the company
- Interviewing and hiring workers
A wide variety of things that have little to do with work or industry are protected by tourist visas. This may include:
- Sightseeing and Tourism
- Holidays
- Visiting with friends or relatives
- Attending social gatherings or non-paid participation in sporting or entertainment events organized by different organizations
- Medical treatment
- Attending short-term, recreational activities
So you see the purpose of both these visas are completely different from each other and one cannot be used as a substitute for the other.
