The M-1 visa is a temporary student visa for persons who want to pursue nonacademic or vocational studies in the United States.
Before you may apply for an M-1 student visa, you must:
Having an approved visa does not mean you will be allowed to enter the United States. A visa allows you to travel to a United States port of entry and request permission to enter the United States. When you arrive at a United States port of entry, an official from Customs and Border Protection (CBP) will grant or deny your admission into the Untied States. If you are granted admission, the CBP official will mark the length of your stay on your Form I-94, Arrival and Departure Card, as D/S for "duration of status." This means that you may remain in the United States as long as you continue your course of study.
To apply for an M-1 visa, you must:
The consular officer will verify your Form I-20 M-N/ID, Certificate of Eligibility for Nonimmigrant (M-1) Student Status and check to see that your data has been entered into the SEVIS system. If the school has not entered your data into the SEVIS system, the consular officer will deny your M-1 visa.
Spouses and unmarried children under the age of 21 of M-1 visa students are eligible to apply for M-2 status to enter the United States. Parents, fiancés, friends, and other relatives must apply for B-2 visitor visa.
