I-94 and Entry to the U.S.
The I-94: Proof of Legal Entry into the U.S.
When entering the U.S., the Customs Border Protection (CBP) officer examines your passport, visa, and immigration documents. Your arrival in the U.S. is recorded in an electronic database. This database contains your electronic Form I-94. You should access and print this I-94 immediately upon arrival to the U.S. To access this record, visit: www.cbp.gov/I94. Some individuals who arrive to the U.S. by crossing a land border will continue to receive a paper I-94 card. In this case, there will not be an electronic I-94 record. The I-94 is a very important documents and is proof of your legal status in the U.S. It also governs your length of stay in the U.S. If there are any discrepancies between your I-94 and other immigration documents (including end date) or if you cannot find your I-94 record electronically, please contact ISS immediately so that we can work with CBP to resolve the issue.
Admit Until Date: Duration of Status (D/S) or Specific End Date
J-1 & J-2: Scholars, employees, and their dependent family members in J status should receive an I-94 record with an admit until date of "D/S" or "duration of status." This means that they may remain in the U.S. as long as they continue their research/employment at KU and their DS-2019 (J-1) has not expired.
Employees in H-1B, O-1 or TN status and their dependent family members will receive a specific end date on Admit Until date on the I-94 record and this end date should match the end date on the I-797 Approval Notice. If there is a discrepancy between the end date listed on the I-94 record and the end date on the I-797 Approval Notice, please contact ISS immediately. In some circumstances your I-94 record will be truncated upon arrival to the U.S. to match the expiration date of your passport rather than the I-797 Approval Notice, if this happens you must contact ISS as soon as possible to discuss resolving the issue. This will likely result in travel outside of the U.S. and re-entry once you have renewed your passport or an H-1B extension may be possible in some circumstances. In order to avoid this situation it is best to have your passport renewed prior to returning to the U.S.
