Here are the various visa categories based on your purpose of visit.

Tourist Visa: This Type of visa is only granted to tourists whose sole purpose of visit is to travel and not engage in any form of commerce. When you plan a vacation to a foreign country, whether alone or with your family, you will need to apply for a tourist visa. Such visas are still more easily obtained. In addition to the required documents, you must provide proof of your hotel stays and return flight tickets, as well as a certain specified amount in your bank account, to demonstrate to the local authorities that you will be in charge of yourself during your visit to their country.

Single Entry Visa : A single entry visa is only good for one trip to the country of destination. No matter the reason for your trip, you are only allowed one entry while your visa is still valid. If your visa is still valid but you have already been to the nation once, for example, you will still be ineligible to travel there again.
