Student I-94 Problem
Recently I received the following question:
"I am on F1 status, and I'm doing my masters. Recently, I checked that my I94 was expired. I have 4 years of my visa left."
As an F-1 student your original I-94 should have been marked "D/S" with no expiration date. Customs and Border Patrol (CBP) either made a mistake or had concerns about your entry and wanted to review your status at a certain time. Discuss your specific situation with your DSO, including whether you should go to the CPB at your airport to correct the I-94, or whether simply departing and returning with a new I-94 would cure the problem. In addition to your visa you also need a current I-20 which the DSO provides.
