Congratulations! If you have decided to pursue your academic career as a full-time student in the United States, you will need either a F or M Visa.
F-1 Student Visa
The F-1 Visa (Academic Student) allows you to enter the United States as a full-time student at an accredited college, university, seminary, conservatory, academic high school, elementary school, or other academic institution or in a language training program. You must be enrolled in a program or course of study that culminates in a degree, diploma, or certificate and your school must be authorized by the U.S. government to accept international students.
