EB2 "Category reach maximum amount of visa" 是啥意思？

EB2,老婆是主申請人，2個星期前485 approval,綠卡收到。
本人向USCIS 打電話詢問本人的case status, ( few hundred number earlier than hers), 今天收到email reply:

Case type:
-- I485

Filing date:
-- 05/03/2007

Type of service requested:
-- Outside Normal Processing Times

The status of this service request is:
USCIS is aware that according to the Department of State?s Visa Bulletin, there appear to be visas available however there has been an extremely large volume of case requiring visas. Therefore your category may have already reached the maximum amount of visas available, so please continue to watch the Visa Bulletin in the future to check for visa availability for your category.


請問這個回複是啥意思？到底是排期準還是限額準呢？？
