Visas can only be "extended" or "renewed" outside of the United States
Visas are only used as a pass that allows you to come to the border of the U.S.
Your I-20, or DS-2019, is what allows you to actually enter and remain here legally,
a valid visa is not needed to maintain your status once you are in the US
Visa renewal, when needed, is best done at the U.S. Embassy in your home country
Procedures and requirements for visas can vary slightly between countries and are
often subject to change - please view your countries US Consulate or embassy web site
for specific requirements
Visit the Web site www.travel.state.gov to determine the procedures for applying for a visa at the U.S. Embassy or consulate
in the country where you wish to renew.
If you are traveling to another country from the United States you must check with
a Visa company or that countries consulate or embassy to see what you need to enter
Passports can be renewed at your government's embassy in the United States or in your
home country. You will need to search for the embassy that is closest to Columbus
but most countries have an embassy in Atlanta.
