Admit Until Date (AUD):This is the end of your Period of Stay and is found on your I-94. If you haven’t travelled outside the U.S. since before September 15, 2026, your I-94 Admit Until Date will still say “D/S”. Knowing and being mindful of your Admit Until Date is important for maintaining your immigration status. Check your I-94 each time you travel as your Admit Until Date may change. Check for any F-2 or J-2 dependents as well. Note: Your AUD includes the period of preparation for departure.
Duration of Status (D/S): Before September 15, 2026, individuals admitted to the U.S. in J and F status were admitted for the “duration” of their status. This rule has been changed by the U.S. government. If you entered the U.S. before September 15, your I-94 will still show “D/S” to mean duration of status. If you travel after September 15, you will be admitted for a fixed period of stay.
Extension of Stay (EOS): EOS is a formal application to the government through USCIS to extend the period of stay for things like a program extension, Optional Practical Training (OPT) for F-1s, or Academic Training (AT) for J-1s.
Period of Stay: This is the length of your immigration status. It is tied to your program of study and period for preparation for departure, not to exceed 4 years. This means students whose program of study will extend more than 4 years into the future may need to take formal action to extend their period of stay beyond that point.
Program End Date: This is found on your I-20 or DS-2019. This end date is the estimated end of your program, likely from when your document was created. Your Program End Date and Admit Until Date will likely be different. Keeping track of both are important to maintaining your immigration status.
Period of Preparation for Departure: The period of stay includes time to prepare for departure after completing your program: 30 days. This is part of the period of stay and the AUD should reflect this additional time. Students whose I-94 AUD remains “D/S” have a 60-day period of preparation for departure. This was formerly referred to as “grace period.”
Unlawful Presence: Maintaining your immigration status is more important than ever. DHS implemented new policies that will make it even more difficult to fix an immigration status violation. This is part of the important changes related to the new rule. Your I-94 will have a fixed end date rather than D/S (duration of status) which it has had in the past.
If you stay in the U.S. beyond the end of your I-94 period (AUD), you would not be considered in legal immigration status. This can lead to the accrual of days of unlawful presence and in extended cases, deportation proceedings. Also, accruing days of unlawful presence can result in being barred from the U.S. for many years, or even permanently.
