請教8老師：
我的H1B extension遞交的時候同時遞交了老公和女兒的H4 extension, 我的批準後顯示的due date 是2018年七月底，這個沒有錯，我們的申請都於2015年11月批了下來。因女兒2016年二月底滿21歲，所以她的due date 是她的生日，但是老公的due date 也被訂到女兒21歲生日那天，是否不對？我理解他的應該和我的due date 是同一天？
所以去年年底我們去了當地的uscis和officer麵談，她幫我們遞了一個inquiry，要求糾正，we submitted a Typographical Error Corrections Request for your form I-539，可是一直到二月底還是沒有得到回複，於是我又打電話再次inquiry，終於在6/9/16 收到email回複：
Below is a summary of what we found and how the issue has been or may be resolved.
On 06/07/2016, after you inquired concerning your I-539, case; a check of our electronic systems indicated your case was approved on 11/03/2015, and your Approval Notice was sent to the address of record. Your Approval Notice was returned as undeliverable.
Also note, the Informational Error of your concern was addressed by the adjudicating officer; per the I-539, Application to Extend/Change Nonimmigrant Status Instruction you may include your spouse and your unmarried children under age 21, years as co-applicants on your application. You may refer to the I-539, Application to Extend/Change Nonimmigrant Status Instruction for additional information.
但是我們一直沒有收到糾正以後的h4, 請問我們下一步應該怎麽辦？
現在我們全家在等485的最後審批，所以每個人都有EAD, 但是2016年9月初就過期了，我沒有用EAD，在用 H1B工作，我女兒在用EAD讀community college，這個h4 的問題會不會影響到全家的EAD extension application?
謝謝您！
