The U.S.A. issues different types of visas to temporary visitors, including students. As a full-time student, you would receive an F-1 or M-1 visa. Most students fall under the F1 category. The temporary visas are also known as non-immigrant visas.
The spouse and children would receive F-2 or M-2 visas.

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

Procedure

1. Get your passport made. Follow this link for detailed information regarding how to obtain your passport. (Passport/NADRA web links……..)
2. Once an academic institute has accepted you for admission to full-time study, they will send you a document known as the I-20 form, which is extremely necessary for the application for a student visa. This form I-20 contains information about how much financial responsibility you will need, what is going to be the duration of your studies, etc.
3. You may need to show the proof of financial support if you or your parents are going to fund your studies in USA. A bank letter stating the available credit balance and the last six months bank statement are the proof of financial support.

An “Affidavit of Support" should be submitted to the U.S. Embassy or Consulate if the studies are going to be sponsored by your relatives or others. Complete this form with information about your sources of financing (letter of sponsorship), and submit it along with your other supporting documents. The embassy may require a letter from the bank that holds the funds.

• Sponsorship letter.
• 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.

Maintaining Visa Status After Arrival

If a student on a F-1 visa is not able to complete their studies by the expiration date on the I-20 form, they must apply to the school's Foreign Student Advisor for an extension 30 days before expiration. Extensions are normally granted for academic and medical reasons so long as there have been no violations of visa status.

It is possible to transfer schools after arrival on an F-1 visa. You will need to notify your current school of the transfer and obtain an I-20 form from the new school. You will complete the student certification section of the I-20 and must deliver it to the foreign student advisor at the new school within 15 days of beginning attendance at the new school.

If you are changing majors at your current school, you do not need to notify the INS. If you are changing degree programs (e.g., from a bachelors degree to a masters degree program), however, you will need to get a new I-20 and submit it to the foreign student advisor within 15 days of beginning the new program.
