The Immigration and Nationality Act provides two nonimmigrant visa categories for persons to participate in exchange visitor programs in the United States.

The "F" visa is for academic studies, and the "M" visa is for nonacademic or vocational studies.

Background requirements
Scholastic Preparation: The student visa applicant must have successfully completed a course of study normally required for enrollment. The student, unless coming to participate exclusively in an English language training program, must either be sufficiently proficient in English to pursue the intended course of study, or the school must have made special arrangements for English language courses or teach the course in the student's native language.

Financial Resources: Applicants must also prove that sufficient funds are or will be available from an identified and reliable financial source to defray all living and school expenses during the entire period of anticipated study in the United States. Specifically, applicants must prove they have enough readily available funds to meet all expenses for the first year of study, and that adequate funds will be available for each subsequent year of study. The M-1 student visa applicants must have evidence that sufficient funds are immediately available to pay all tuition and living costs for the entire period of intended stay.

Acceptance Form: An applicant coming to the United States to study must be accepted for a full course of study by an educational institution approved by the Immigration and Naturalization Service (INS). The institution must send to the applicant a Form I-20A-B, Certificate of Eligibility for Nonimmigrant (F-1) Student Status for Academic and Language Students. The nonacademic or vocational institution must send to the student a Form I-20M-N, Certificate of Eligibility for Nonimmigrant (M-1) Student Status For Vocational Students. Educational institutions obtain Forms I-20A-B and I-20M-N from the INS.

Visa Ineligibility/Waiver
The nonimmigrant visa application Form OF-156 lists classes of persons who are ineligible under U.S. law to receive visas. In some instances an applicant who is ineligible, but who is otherwise properly classifiable as a student, may apply for a waiver of ineligibility and be issued a visa if the waiver is approved.

Applying for a student visa
Applicants for student visas should generally apply at the U.S. Embassy or Consulate with jurisdiction over their place of permanent residence.

Although visa applicants may apply at any U.S. consular office abroad, it may be more difficult to qualify for the visa outside the country of permanent residence.

Required Documentation: Each applicant for a student visa must pay a nonrefundable US$45 application fee and submit:

1. An application Form OF-156, completed and signed. Blank forms are available without charge at all U.S. consular offices;
2. A passport valid for travel to the United States and with a validity date at least six months beyond the applicant's intended period of stay in the United States. If more than one person is included in the passport, each person desiring a visa must make an application;
3. One photograph 1 and 1/2 inches square (37x37mm) for each applicant, showing full face, without head covering, against a light background; and
4. For the "F" applicant, a Form I-20A-B. For the "M" applicant, a Form I-20M-N.
5. Evidence of sufficient funds.

Other Documentation: Student visa applicants must establish to the satisfaction of the consular officer that they have binding ties to a residence in a foreign country which they have no intention of abandoning, and that they will depart the United States when they have completed their studies. It is impossible to specify the exact form the evidence should take since applicants' circumstances vary greatly.

U.S. Port of Entry
Applicants should be aware that a visa does not guarantee entry into the United States. The INS has authority to deny admission. Also, the period for which the bearer of a student visa is authorized to remain in the United States is determined by the INS, not the consular officer. At the port of entry, an INS official validates Form I-94, Record of Arrival-Departure, which notes the length of stay permitted.

Additional Information
Employment: An F-1 student may not accept off-campus employment at any time during the first year of study; however, the INS may grant permission to accept off-campus employment after one year. F-1 students may accept on-campus employment from the school without INS permission. Except for temporary employment for practical training, an M-1 student may not accept employment.

Family Members: A spouse and unmarried, minor children may also be classified for a nonimmigrant visa to accompany or follow the student. Family members must meet all visa eligibility requirements, including evidence that they will have sufficient funds for their support, and that they will depart the U.S. when the student's program ends. Spouses and children of students may not accept employment at any time.

Further Inquiries
Questions on how to obtain Forms I-20A-B and I-20M-N should be made to the educational institution. If the institution does not have the forms, it needs to contact the local INS office. Questions on visa application procedures at the American consular offices abroad should be addressed to that consular office by the applicant.
