请教PJIANG, 863211老师,一个问题.谢谢!

Initial Review

The I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS was transferred and is now being processed at a USCIS office. You will be notified by mail when a decision is made, or if the office needs something from you. If you move while this case is pending, please use our Change of Address online tool to update your case with your new address or call our customer service center at 1-800-375-5283

一般情况下,这通常是什么问题?需要多长时间能得到结果?
谢谢!
