What is F-1 Status?
|Your F-1 lawful status is the official U.S. government designation and authorization of your stay in the U.S. as a non-immigrant student.|
Your status is designated by the Customs and Border Patrol officer who reviews your visa and other documents at your port of entry, and upon your admittance, writes your lawful immigration status and the length of time you may remain in the U.S. on your Form I-94 and Form I-20 (shown below).
"D/S" means "duration of status" or until the completion date noted on your I-20 providing you continue to MAINTAIN THE REQUIREMENTS as your STATUS.
In most instances, your lawful status and visa category will be the same as F-1, unless you change your status after entering the U.S.
Immigration matters are the responsibility of the U.S. Department of Homeland Security.
