In some countries (especially among the upper class), musical training is becoming a sought after commodity. Parents looking to develop their children’s musical abilities are ready to pay qualified instructors to teach their children various instruments and musical theory. Teaching music could be approached in one of two ways! First, one could offer music lessons on a private basis from their home or going into the homes of the students. This can be excellent for those who do not wish to develop an entire business but would like to make some extra money and relationships in the community. You may not be able to obtain a residency visa on this first idea. Second, one could develop a musical training school, which would offer set lessons and training students. This idea would require have more running expenses, but could provide employment for multiple teachers and would allow you to obtain a residence visa. One note of caution, make sure that your teachers are qualified and can instruct at a level that is required by the students.
