There are a number of similarities between a passport and a visa, but there are also substantial differences between the two. A passport is needed for travel to any international destination, no matter what route a resident of the United States of America selects for their travel plans. A visa is only needed for travel to certain countries. American travelers do not need to obtain a visa if they are traveling through Europe, although depending on the county, a visa may be needed for visits lasting thirty to one hundred and eighty days in a single country.
A passport is
issued by the country from which the traveller departs. A visa is issued
by the country to which to traveler arrives.
Although any
international travel will require a passport, a travel agent or a person
who works in a country's embassy or consulate can be an invaluable
resource for individuals who want to find out if they will need to
obtain a visa to visit a country.
There are fourteen common visa
categories, although not every kind of visa is offered by each country.
The common visa types are a transit visa, a tourist visa, a business
visa, a temporary worker visa, an on-arrival visa, a spousal or partner
visa, a working holiday visa, a diplomatic or official visa, a courtesy
visa, a marriage visa, and an immigrant visa, as well as a pensioner,
retiree or retirement visa.
