An entry VISA is a travel document issued by a U.S. Consulate and attached to a page in your passport that is evidence of your eligibility to be admitted to the United States in a particular status with supporting documents. After admission to a program of study, International students who require an F-1 student visa to study in the U.S. apply for a certificate of eligibility called an I-20 from the International Students and Scholars office (ISSO). The I-20 is needed to apply for the entry visa to present upon arrival.
The two most important requirements are to remain registered full-time every term, making normal progress toward your degree, and not to accept any employment, either on- or off-campus, without written permission from the ISSO, and, if necessary, authorization from the Department of Homeland Security (DHS). Be familiar with the information in Maintaining F-1 status. Under certain conditions status may be reinstated if lost for reasons beyond your control. You may also regain status by leaving the U.S.
An entry visa in your passport is relevant ONLY to your eligibility to be admitted to the U.S., not for remaining in the U.S. What matters while you are in the United States is maintaining your F-1 status for the duration of your academic program as reflected on your I-20. If your entry visa expires while you are in the U.S. you will have to obtain a valid one before re-entering the U.S. from a trip abroad. You cannot renew a visa in the U.S. but will have to apply for a new one at a U.S. consulate abroad, most likely in your home country.
If you are leaving the U.S. during your program of study, you need an unexpired passport, unexpired F-1 entry visa, and an I-20 which has a travel signature obtained from the International Students and Scholars Office (ISSO) on page 3 that is less than 12 months old at the time that you return. Please read Travel and Re-entry in F-1 Status for more information.
Remember to have your I-20 on your person and not packed away in checked luggage since you go through inspection before claiming bags. That said, if you forget your I-20, you should ask the immigration official for an I-515 upon entry, which will allow your admission in F-1 status for 30 days. With an F-1 visa you are normally admitted to the U.S. For 'duration of status' (D/S,) but if you are missing the I-20 it is most likely you will be admitted for 30 days with an I-515.
The Office of Global Programs provides basic visa advice for study abroad candidates. Whether you need a visa to visit a third country almost always depends on your nationality, not your status as a student in the U.S. You will have to look at the website of the embassy of the country you wish to visit to see their requirements for visitors. Columbia is conveniently located in New York City where you can easily visit the consulates from around the world if you do need to apply for a visitor visa.
No. A support letter is not required by the U.S. Consulates for visitor visa applications. As a visitor to the United States, it is important for you to be aware of visa requirements. Citizens of certain countries that participate in the Visa Waiver Program may come to the United States without a visa if certain conditions are met. Other visitors will need a nonimmigrant visa. We encourage you to visit the U.S.
We recommend you secure reservations off-campus. For a list of hotels that give a Columbia rate, please visit the Travel Portal and click on hotels on the left menu. Budget friendly options near campus include:
Interning and volunteering offer opportunities to gain experience, build your skills, and strengthen your resume. For unpaid work on or off campus such as volunteering or an unpaid internship, you may start right away and do not need OPT. You must be sure the position is unpaid for anyone (i.e. not just you because you want to take the job as a volunteer). Start by using these tools:
