尊敬的8老師：
http://travel.state.gov/content/visas/en/immigrate/immigrant-process/interview/prepare.html
我在上麵這個地方學習《Prepare for the Interview》，
在麵簽要準備的材料列表中，有下麵的話：
□ EVIDENCE OF SUPPORT: The Consulate requires evidence that demonstrates you and the members of your family who will accompany you are not likely to become public charges after immigrating to the United States. Please prepare the documents listed below for your visa category. Even if you comply with these requirements, a consular official may at any time require additional evidence to determine your eligibility. Immediate relative (CR/IR) and family preference (F) cases: An original I-864 (or I-864EZ, if applicable) signed by the petitioner must be submitted with his or her most recent Federal income tax return.
我的問題是：864表的原件已經寄給NVC了，我手中沒有原件啊，這可怎麽辦呢？
另外，這些材料列表，我是否要按照材料列表的順序排列好這些文件？
還有個問題是：
12月4號收到了讓父母去廣州麵簽的通知，12月16號我們搬家。
此前填寫的父母來美國後的住址，全是我搬家前的。父母這個月麵簽後，進入美國時，填寫的美國住址，可以不可以還寫我沒搬家前的地址？
非常感謝8老師！
麵簽的日子近了，心情很緊張，離成功不遠了，8老師辛苦了！！！
