可是我通知郵局把信轉到我的新的地址了）。
-All the correspondences from USCIS are unforwardable by 郵局 (have to be returned to USCIS).
要再寄，Form I-824並付400多大刀。幫我看看我該幅這筆錢嗎？
-You may have to file the I-824 if you need the duplicate. But I really do not think you have to have the h4 approval notice in hand. You can print out the approval information online using your H4 applicaiton receipt number which can prove your legal status. If you extend your H4 in the future, just provide the H4 applicaiton receipt and the online approval information as the proof of your status. If you visit China, just provide the old I-94 card (e.g. your old H4 I-94) to the airlines even if the I-94 has expired. Then, you can use your spouse's H1 approval notice to apply for the H4 visa to come back.
有什麽辦法argue? 謝謝了。
注；新的學校很奇怪，幫我和老婆file了我們的H簽證申請後，卻隻管我的H1, 不管老婆的H4，
-The H4 is yours, not related to the school. So, it is vcery normal that the school did not care about your H4.
和我一以前的學校不一樣，以前的學校統統管.
