请教8老师，皮老师或有经验的朋友

我在为妹妹申请移民。早在2002年递交全部申请材料后就收到I130 approved Form，一直排队至今。最近收到USCIS的email，内容如下：

Your Case Status: Post Decision Activity

On June 11, 2015, we approved your Form I130, IMMIGRANT PETITION FOR RELATIVE, FIANCE(E), OR ORPHAN。We will mail your approval notice.

For approved applications/petitions, post-decision activity may include USCIS sending notification of the approved application/petition to the National Visa Center or the Department of State. For denied applications/petitions, post-decision activity may include the processing of an appeal and/or motions to reopen or reconsider and revocations.

敬请8老师，皮老师或有经验的朋友看看，这次的approval notice是否指排期approved.

万分感谢！
