Do I Need a Student Visa?
A student visa is a requirement in the United States if your course of study is more than 18 hours per week. In other words, most full-time students and the majority of part time students need a student visa.
When Do I Apply for a Student Visa?
Applying for a student visa can take time, so it is important to start the application process early. If this is your first time applying for a student visa, an in-person interview may be required. The summer months are the busiest months for student visa applications--keep this in mind when you are applying.
Most Embassies and Consulates refuse to issue a student visa more than 120 days prior to your course registration or start date. If you apply before then, your application will be held until the appropriate time. It is okay to apply early, as this will give the Embassy or Consulate extra time to work through special requirements.
