情況如下：
我是美國公民，在去年6月用親屬移民同時為父母申請綠卡。上周收到信，說兩個人485都批了。昨天已經收到母親的綠卡。但是今天收到信，說父親的case is reopened: We have reopened your case, or reconsidered the decision previously issued on your case. We will notify you in writing when we make a decision on your case or if we need additional information.
我明白父親的批準被收回了，現在需要重新考慮，可能要求新的資料。現在老人和我的心情都很忐忑，擔心母親被批準而父親被拒。
請問老師，一般會出現什麽樣的問題，什麽情況下申請可能被拒絕？請問各位朋友是否有類似的經曆？
-Most likely it is a mistake. It is not unusual that some IO sometimes mixed the thing up and sent you the wrong message. So, you may contact USCIS to see what happened or just wait. I don't think it is serious.
後來情況怎樣了？我隻能想到的因素隻有父親年齡過80歲了，母親還沒有。謝謝大家！
