Student Visas, as the name suggests are visas issued to applicants whose primary purpose of visit to the country is the pursuit of education.... These could vary in terms of the requirements of documents to the different proof of funds acceptable to what all the visas would let you do apart from studying in the country
A student visa (F or M) is required to study in the United States. Foreign nationals may not study after entering on a visitor (B) visa or through the Visa Waiver Program (VWP), except to undertake recreational study (non-credit) as part of a tourist visit.For short periods of recreational study, a Visitor (B) visa may be appropriate
A visitor (B) visa permits enrollment in a short recreational course of study, which is not for credit toward a degree or academic certificate. Study leading to a U.S. conferred degree or certificate is never permitted on a visitor (B) visa, even if it is for a short duration. For example, a student in a distance learning program that requires a period of time on the institution’s U.S. campus must obtain a student (F or M) visa prior to entering the United States.When should I apply for a Student Visa?
Studying abroad requires meticulous planning to say the least. Students are always advised to plan their admission/ application process keeping in mind university deadlines and working backwards. Students are required to appear for English eligibility tests as per the university policy and also have required documents in place for the smooth processing of their application. Hence, students are always advised to apply 3-4 months in advance to avoid any last-minute rush. Candidates seeking financial aid, scholarships and education loans should add another couple of extra months to the process as these applications take more time.
Different countries have different requirements. Here are some quick links to Student Visa Guides for the Top Study Abroad Destinations, Interview Guide for F1 Visa and SPP and non-SPP requirements.
