What is a visa?
A visa is a permit issued by a country to someone allows the person into the country stating clearly the purpose of the visit and the duration of the stay. Visas are associated closely with the request for permission to enter or exit a country and the conditions pertaining to this vary with the country one chooses to visit.
How does it work?
Visas generally work through the simple rule of seeking permission from the country one wishes to visit. For example, a non-EU tourist who wishes to visit Spain generally must first obtain a Spanish Tourist Schengen Visa. Nationalities within the Schengen Area can freely travel between all member countries without a visa.
There are different types of visas but the most common include; the transit visa which lasts for less than three days and issued for people passing through a country to another stop. The tourist visa to people who wish to travel for leisure. There is also business visas issued to those who wish to engage in commerce in another country.
Several countries across the globe including the United States of America, Singapore, and Japan require adult passport holders to be fingerprinted on arrival.

So many nations in the world require that the visitor is checked if he or she has any record of criminal history in his or her native country or any other country. If the person is found to have any criminal history he or she may be barred from entering the particular country of interest. Most data can be found via your passport ID.

For countries like Chad, Uganda, Benin they require visitors to be vaccinated before traveling and upon arrival, they are required to produce a current International Certificate of Vaccination as evidence. In other countries, visitors are required to be vaccinated if they are coming from an infected area or nation.
Many nations, even if the passport holder has free access to that country, have to make sure that the visitor has enough funds to spend while in the country. In addition to this, they may also require the visitor to show evidence of ticket of exit.
In as much as the holders of passports with visa-free access to certain countries can freely travel there, there are certain restrictions each country places for them to allow visitors into their country. Make sure to check the entry requirements or call the country’s embassy before buying flight tickets.
