我认真地核对我的I-797，结果如下：Receipt date:April 13,2010,Priority date:July 16,2009,Notice date:May 14,2010,Notice type:Approval Notice.
-Then, this is the approval notice and it is very unfavorable to your child because your I-140 was approved so fast and it was very rare if not using premium processing.
我是单位支持以Perm 第二优先办理绿卡的，即从劳工卡到I-140，我不知道他们是否以加快方式办理I-140的，2010年5月份单位律师通知我I-140得到批准。
我的I-140 pending date等于Notice date减去Receipt date 还是Notice date减去Priority date？这意味着我儿子有一个月还是十个月的缓冲期到移民意义上的21周岁。
-Only one month. So, your child probably will be age-out unless your PD will be current in Feb. 2012.
请8老师指教，关于我儿子年龄的问题，我需要单独向移民局递交申请还是随I-485一起递，何种表格？
-He can file his I-485 together with yours if the PD is current.
需要准备哪些材料？
-See:
好像移民局不是“自动地”减去我的儿子年龄小于21 岁。
-Just explain it in the cover letter by saying "base on Child Status Protection Act, your son (name) is qualified for applicaiton Application to Register Permanent Residence or Adjust Status, etc. though his age is > 21".
