Before you read any informative stuff  in this category on Tej Kohli Blog, Let’s first concentrate on the most fundamental question that I’m sure must have cropped up in your minds at some time or the other..What exactly IS a Visa???

A stamp in the passport issued by an American Embassy or Consulate abroad, allowing the holder to request entry to the United States in a certain visa status within the time period specified on the visa. A visa may allow one, two or multiple entries before the expiration date of the visa.

A visa is either a multicolored stamp or computerized document affixed to a page in the passport by a U.S. Consular office abroad. It allows international visitors to travel to the U.S. as long as the visa has not expired. Once visitors are admitted into the U.S., visas are no longer the most important documents governing their status. A visa is used only for travel to the U.S., but is not used to determine how long individuals may stay in the U.S.

A seal or endorsement made on a passport by the proper officials of a country that entitles the bearer to apply for entry into another country at the port of admission.

A visa allows a foreign citizen to travel to a U.S. port-of entry and request permission from the U.S. immigration officer to enter the United States. It does not guarantee entry into the U.S.

Those were some definitions of Visa on the web ..hope the article was helpful. More in subsequent posts.
