Students are encouraged to apply for their visa early to provide ample time for visa processing. Students may apply for their visa as soon as they are prepared to do so.
The consular officer may need to get special clearances depending on the course of study and nationality of the student. This can take some additional time. For more information on applicants who may have additional processing requirements see Special Processing Requirements.
Students should note that Embassies and Consulates are able to issue your student visa 120 days or less, in advance of the course of study registration date. If you apply for your visa more than 120 days prior to your start date or registration date as provided on the Form I-20, the Embassy or Consulate will hold your application until it is able to issue the visa. Consular officials will use that extra time to accomplish any of the necessary special clearances or other processes that may be required.
Students are advised of the Department of Homeland Security regulation which requires that all initial or beginning students enter the U.S. 30 days or less in advance of the course of study start/report date as shown on the Form I-20. Please consider this date carefully when making travel plans to the U.S.
A student who wants an earlier entry into the U.S. (more than 30 days prior to the course start date), must qualify for, and obtain a visitor visa.

All applicants for a student visa must provide:

Form I-20A-B, Certificate of Eligibility for Nonimmigrant (F-1) Student Status-For Academic and Language Students or Form I-20M-N, Certificate of Eligibility for Nonimmigrant (M-1) Student Status for Vocational Students.You will need to submit a SEVIS generated Form, I-20, which was provided to you by your school. You and your school official must sign the I-20 form. All students, as well as their spouses and dependents must be registered in the Student and Exchange Visitor Information System (SEVIS), an Internet-based system that maintains accurate and current information on non-immigrant students and exchange visitors and their dependents (F/M-2 visa holders). Your school is responsible for entering your information for the I-20 student visa form into SEVIS. Students will also have to pay an SEVIS I-901 fee for each program of study. Questions regarding your exchange program should be directly to your program sponsor;
A completed application, Nonimmigrant Visa Applicant, Form DS-156, together with a Form DS-158. Both forms must be completed and signed. Some applicants will also be required to complete and sign Form DS-157. A separate form is needed for children, even if they are included in a parent's passport.
An interview at the embassy consular section is required for almost all visa applicants. The waiting time for an interview appointment for applicants can vary, so early visa application is strongly encouraged. During the visa interview, a quick, two-digit, ink-free fingerprint scan will be taken, as well as a digital photo. Some applicants will need additional screening, and will be notified when they apply.
A passport valid for at least six months after your proposed date of entry into the United States.
One (1) 2x2 photograph.
A MRV fee receipt to show payment of the visa application fee, a visa issuance fee if applicable and a separate SEVIS I-901 fee receipt. While all F visa applicants must pay the MRV fee, including dependents, only the F-1 principal applicants must pay the SEVIS fee.

All applicants should be prepared to provide:

Transcripts and diplomas from previous institutions attended;
scores from standardized tests required by the educational institution such as the TOEFL, SAT, GRE, GMAT, etc.;
Financial evidence that shows you or your parents who are sponsoring you have sufficient funds to cover your tuition and living expenses during the period of your intended study. For example, if you or your sponsor is a salaried employee, please bring income tax documents and original bank books and/or statements. If you or your sponsor own a business, please bring business registration, licenses, etc., and tax documents, as well as original bank books and/or statements.

Applicants with dependents must also provide:

Proof of the student’s relationship to his/her spouse and/or children (e.g., marriage and birth certificates.);
it is preferred that families apply for F-1 and F-2 visas at the same time, but if the spouse and children must apply separately at a later time, they should bring a copy of the student visa holder’s passport and visa, along with all other required documents.

Additional Information

No assurances regarding the issuance of visas can be given in advance. Therefore final travel plans or the purchase of nonrefundable tickets should not be made until a visa has been issued.
Unless previously canceled, a visa is valid until its expiration date. Therefore, if the traveler has a valid U.S. visa in an expired passport, do not remove the visa page from the expired passport. You may use it along with a new valid passport for travel and admission to the United States.

Students Away from Classes More Than Five Months

Students in or outside the U.S., who have been away from classes for more than five months, will likely need a new visa to enter the U.S.

When you enter the United States on a student visa, you will usually be admitted for the duration of your student status. That means you may stay as long as you are a full time student, even if the F-1 visa in your passport expires while you are in America. For a student who has completed the course of studies shown on the I-20, and any authorized practical training, the student is allowed the following additional time in the U.S. before departure:

F-1 student - An additional 60 days, to prepare for departure from the U.S. or to transfer to another school.
M-1 student - An additional 30 days to depart the U.S. (Fixed time period, in total not to exceed one year). The 30 days to prepare for departure is permitted as long as the student maintained a full course of study and maintained status. An M student may receive extensions up to three years for the total program.

The restrictions are:

Students who attend public high schools in the U.S. are limited to twelve months of study. Public school attendance in the U.S. prior to November 30, 1996 does not count toward this limit.
F-1 visas can no longer be issued to attend public elementary or middle schools (Kindergarten - 8th grade) or publicly-funded adult education programs.
Before an F-1 visa for a public school can be issued, the student must show that the public school in the U.S. has been reimbursed for the full, unsubsidized per capita cost of the education as calculated by the school. Reimbursement may be indicated on the I-20. Consular officers may request copies of canceled checks and/or receipts confirming the payment as needed.
