請教8老師一個給配偶申請綠卡的問題：
我配偶是澳洲公民，去年以免簽來美與我結婚。結婚後我提交了EB1a 485調身份的申請，但當時由於配偶是免簽及結婚時間短無法為其提交485。我的綠卡在去年底拿到。現在我配偶以B2簽證來美，我想在她來美3個月後在美國境內遞交485調整身份，有問題不甚明白：
1. 給配偶提交485申請時需要什麽材料？
-Read the I-485 instructions. Normally, the copies of her birth certificate, your marriage certitificate, copy of your I-140 approval/receipt notice, copy of your I-485 receipt, etc. Other documents are similar to yours.
需要填824 Follow to join嗎？
-No.
2. 提交485後必須在B2到期前離境嗎？
-No. She is legal to stay in US after I-485 filing. She can not leave US unless she has approved advance parole.
可不可以申請B2延期?-No.
多謝！
