Is a Visa the same thing as a Passport?
No, a Visa is permission granted by the government of a country to an alien to enter that country and to remain for a specific period of time. It is the responsibility of the traveler to obtain necessary visas, if any, before proceeding abroad. Visas are obtained from the embassy or consulate of the countries to which the applicant wishes to travel.
A Passport is require to travel to and from those countries from which the Visa is granted.
