LG EB2，485 去年10月份递交，上个星期收到email说LG和我都要补件，今天律师收到信，其中退回了体检表，原文如下：
The Form I-693, Medical Examination of Aliens Seeking Adjustment of Status and the Supplemental Form to I-693 submitted with your application were not signed by a civil surgeon and are therefore unacceptable.
Your original Forms I-693 and supplemental form to I-693 are hereby returned to you in the enclosed sealed envelope. Take this letter and your enclosed forms to the civil surgeon who conducted your medial examination. ONLY THE CIVIL SURGEON SHOULD OPEN THE SEALED ENVELOPE.
The forms must be signed by the civil surgeon, and annotated with the appropriate designation (e.g. M.D.). Photocopied signatures or an RN or PA signature will not be acceptable.
IMPORTANT WARNING: only a designated civil surgeon is able to conduct your medical examination. After the examination, the civil surgeon should complete, sign and date the forms, then seal them in his/her professional envelope, and give them to you to be returned unopened to this office with any other requested evidence.
问题是，我们拿着没拆封的体检表到医生那儿，拆开一看是签了字的，好好的为什么要退呢？那个医生也是USCIS网站上找到的，我们该怎么办呢？
请各位大侠不吝赐教！
