本人公民，太太三个月拿到了绿卡，非常顺利。但是两个孩子一直不顺，要各种材料。去年圣诞节附近收到了粉红的单子，内容是如下。
诡异的是：1. 说体检超过了60天。难道不是两年有效吗？
-Based on the new rule, you need to mail this I-693 to USCIS (with I-485 filing or separately after I-485 filing for Request for Evidence (RFE) by USCIS) within 60 days from the date the doctor signed the I-693.
是不是需要重新体检？
-If you receive Request for Evidence (RFE) from USCIS for this document or you receive the I-485 Interview Notice, just ask the doctor who conducted the physical exam to issue a new signed and sealed I-639 with the exam result, and send it to USCIS for the RFE, or bring it to the IO during the interview.
2. 说不要邮寄材料。但是两个月过去了，杳无音信。问律师，说没见过这种情况，让我们再等。
目前如何行动比较好？
_Wait for RFE or interview. You may call USCIS for the status. Nohting worried.
多谢!!
