P老师，8老师， 我的PD是2007，6月18号，我在2011，10月3号current后打了services request的电话，同时为我和lp都要求了service request。我是主申请人，老婆是485申请的dependent。 10月13号，我老婆首先受到service request的回信，告知她的case已经pre-adjudicated.要求她继续等即可。 Based on your request we researched the status of this case. We are actively processing this case. However, we have to perform additional review on this case and this has caused a longer processing time. If you do not receive a decision or other notice of action from us within 6 months of this letter, please call customer service at the number provided below. 这2封不同内容的信让我很郁闷，如果我lp作为副申请人的case已经preadjudicated，那怎么我的案子又需要additonal review呢，而且提到要求等6个月。 我的信是否说明我的case会被referral或者停滞在name check/backgroud check。我需要做些什么能帮助加速我的case呢？请给一些建议把。
