The three most important documents are your passport, I-94 card and your I-20.
This is your most important piece of identification, and you need to keep it valid (at least six months beyond your projected date of departure from the U.S.) You cannot renew your visa unless your passport is current; neither can you leave the U.S. without a valid passport. It is strongly urged that you photocopy important pages of your passport, i.e., the identification page, the expiration page, and the visa page. Should you lose your passport, having photocopies of important pages may reduce the time needed to replace the document. To renew your passport YOU must contact your country's embassy or consulate. The address and phone number may be obtained through the International Student Office.
This is the entry permit issued by the Immigration inspector at the port of entry into the U.S. This is the little white card which was stapled into your passport upon arrival in the U.S. Keep it there. It is your permit to remain in the U.S. The D/S status marked on the I-94 means that you are permitted to remain in the U.S. for as long as you are pursuing your intended program of study, provided you remain in status, your I-20 has not expired, and you are making satisfactory progress toward completion of your degree.
