Visa granted by a foreign country may be of various types, with different conditions attached to each of them. A Transit Visa allows you to stay in that country just for a day or two, while a Tourist Visa may allow you to stay for periods up to several months. For a Business Visa, the periodicity of the Visa depends on your need to stay in that country. A student Visa is granted to students and is valid generally for the period of study ( including grace period) and permission of work outside university is not allowed. Almost all these Visas will stipulate that you cannot take up a job in that country during the period of your stay.
