A visa is issued by the country that an individual plans to visit. You must first learn the specific travel requirements of that particular country before applying for and receiving a visa. If you are traveling to multiple countries, you need to check with the embassy or consulate of each country.
Visa regulations for foreigners vary from country to country. With certain countries, visitors from specific outside countries may enter without a visa. Some countries require a visitor to obtain a visa from that country's embassy or consulate, within the visitor's own country, before travel. Others issue a visa once the traveler arrives to the country he is visiting.
Visa requirements also vary according to different types of travel reasons. Among others, there are specific visas for travelers who wish to study or train, work, receive medical treatment or take a vacation.
