Form I-94 / Admission Stamp
Prior to April 30, 2013, you have been issued a white paper I-94 that was completed for you by a U.S. customs official at the port of entry. There is an 11-digit ID number on the card. If you were admitted on an F-1 or J-1 visa, your I-94 card is marked “D/S” (Duration of Status) Do NOT lose your paper I-94 card. There is a USCIS fee and a lengthy process to replace it!
If you were admitted in the United States AFTER April 30, 2013, you may NOT have received a white paper I-94, but your passport was stamped with an admission stamp and marked “D/S” for Duration of Status.
