請教PJIANG, 863211老師,一個問題.謝謝!

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

一般情況下,這通常是什麽問題?需要多長時間能得到結果?
謝謝!
