Als je het I-94 formulier niet hebt ingeleverd kan dat zeker problemen gaan opleveren als je niets doet. Een collega van mijn heeft dat ook gehad en heeft toen de instructies opgevolgd die staan in de FAQ van de website van de
US Embassy:
If you returned home with your U.S. Citizenship and Immigration Services (USCIS) departure record Form I-94 (white) or Form I-94W (green) in your passport, it means that your departure was not recorded properly. It is your responsibility to correct this record. You must provide the BCIS sufficient information so we can record your timely departure from the United States. This will close out your earlier record of arrival to this country.
If you do not validate a timely departure from the United States, or if you cannot reasonably prove otherwise when you next apply for admission to the United States, the USCIS may conclude you remained in the United States beyond your authorized stay. If this happens, the next time you apply to enter the United States, your visa may be subject to cancellation or you may be returned immediately to your foreign point of origin.
In particular, visitors who remain beyond their permitted stay in the United States under the Visa Waiver Program cannot reenter the United States in the future without obtaining a visa from a United States Consulate. If this occurs and you arrive at a United States port-of-entry seeking admission under the Visa Waiver Program without a visa, United States immigration officers may order your immediate return to a foreign point of origin.
To validate departure, the USCIS will consider a variety of information, including, but not limited to:
Original boarding passes you used to depart the United States
Photocopies of entry or departure stamps in your passport indicating entry to another country after you departed the United States (you should copy all passport pages that are not completely blank, and include the biographical page containing your photograph.), and
Photocopies of other supporting evidence, such as:
Dated pay slips or vouchers from your employer to indicate you worked in another country after you departed the United States
Dated bank records showing transactions to indicate you were in another country after you left the United States
School records showing attendance at a school outside the United States to indicate you were in another country after you left the United States
Dated credit card receipts, showing your name, but, the credit card number deleted, for purchases made after you left the United States to indicate you were in another country after leaving the United States
Your statement will not be acceptable without supporting evidence such as noted above.
You must mail legible copies or original materials where possible. If you send original materials, you should retain a copy. The USCIS cannot return original materials after processing. To help us understand the situation and correct your records quickly, please include an explanation letter in English. You must send your letter and enclosed information only to the following address:
ACS - INS SBU
P.O. Box 7125
London, KY 40742-7125
USA
Do not mail your departure Form I-94 or supporting information to any United States Consulate or Embassy, to any other USCIS office in the United States, or to any address other than the one above. Only at this location are we able to make the necessary corrections to USCIS records to prevent inconvenience to you in the future. (Rev. IN02-39)
If you are traveling back to the U.S. soon, and are concerned that a mailed I-94 will arrive too late and present a problem at the port of entry, take the I-94 with you, and turn it in to the Immigration officer upon arrival with proof of when you left the US.
