不交回I-94以後會有麻煩

按照下麵要求把I-94和相關文件寄給移民局。

Under U.S. law, all travelers to the United States must return the I-94 or I-94W departure record cards to the appropriate USCIS authorities before departing the United States. A traveler who fails to do so may be recorded as making an untimely departure from the United States. Without an accurate record that you departed the United States within the time set when you entered the country, the USCIS may conclude that you overstayed the period of time granted on admission.

If you are still in possession of the I-94 or I-94W it is your responsibility to ensure that it is surrendered to the appropriate authorities so that your record is corrected and that you do not experience any problems on future travel to the United States as a result.

You are required to complete the back of the card listing the port of departure and date of departure from the United States and the carrier/flight information. The I-94 or I-94W together with a letter of explanation and evidence of your departure from the U.S. should be sent to
ACS - USCIS, SBU, P.O Box 7125,
London, KY 40742-7125,
USA
Do not mail the I-94/I-94W to the Consulate/Embassy as the DHS (Immigration) office does not have the authority to update records.
