那问题来了,父母离境时,原先是要上交i94的,以证明离境时间,现在没有了,怎么办呢?
-Just show the passport to the Airlines and USCIS will find their departure information from the Airlines. See the following at this website:
http://www.cbp.gov/travel/international-visitors/i-94-instructions
".......Upon exiting the U.S., travelers previously issued a paper Form I-94 should surrender it to the commercial carrier or to CBP upon departure. Otherwise, CBP will record the departure electronically via manifest information provided by the carrier or by CBP.....".
If they need I-94 for B2 extension or green card application, they can print it out at this website and provide the printed copy for it:
