What certificates do you need to return from the United States to enter and leave customs?
When you leave the United States, the airline recycles your I94. When you return to China, the Chinese customs will check your passport. When you return to the United States, the United States Customs will check your visa and I20. You must ensure that your visa has not expired, and that the date of signature on page 3 of I20 is not more than one year from the date of your return to the United States. If you return to the United States on January 15, 2011, the last signature on page 3 of your I20 must be after January 16, 2010, or you will be refused entry. I901 is your SEVIS Fee receipt. It doesn't matter whether you take it or not, because I've never been asked about it so many times. If your visa expires before you return to the United States, you must apply for renewal at home. Renewal does not require an interview, just bring your passport, I20 and the school's "official transcript" in CITIC Bank. Baggage will not be sent out when transferring in Japan. Of course, if you want to enter Japan and stay for a few days, your luggage will be sent out. If you just stay for a few hours, you will not be sent out. Is this easy to understand?
