Upon entering or returning to the U.S., you will undergo inspection by a U.S. Customs and Border Protection officer, who will review your passport, F-1 / J-1 visa, and I-20 / DS-2019. Do not use any other visa if you are returning as an F-1 / J-1 student, as entering under another visa may render you ineligible to continue studying.
CBP decides whether to admit non-immigrants into the U.S. The facts and circumstances presented when you enter are the basis of this decision. OIS cannot guarantee that CBP will admit or re-admit you into the U.S.
After arrival, check your I-94 admission record to ensure all information is correct, including your visa type and 'admit until' date (which should always indicate the duration of status, or "D/S").
If your status is incorrect, call the PHL airport's Deferred Inspection Site at 215-863-4247 or email [email protected] with scanned copies of your passport, biographic page, visa, admission stamp, boarding pass, and description of the issue.
