Any international student wanting to study in the USA will need to obtain a student visa for the USA. Most students are issued with an F-1 visa, and the general outline/process flow for obtaining an F1 visa is as follows
Applying for the F-1 student visa may vary depending on the U.S. embassy or consulate you are dealing with. You will be required to pay a non-refundable visa application fee. There is an online visa application available, which allows you to complete and print the Form DS-160 to take to your F-1 visa interview.
Your F-1 visa interview will determine whether you are qualified to receive an F-1 student visa for the USA. Assuming that you have prepared the appropriate documents and meet all of the F-1 visa requirements, your visa will be approved at the discretion of the consular officer.
