提交follow to join 485 時，能不能選在主申請人的485還在pending期間？
-Yes, the derivative can file I-485 during the primary applicant's I-485 is pending as long as the priority date is current.
假設副卡 follow to join 485 剛剛提交不久，主申請人就綠了。這種情況下，uscis會不會因為副卡 485在交表時主申請人還沒有綠，就直接鋸掉，
-No. But it will not be approved until after the primary applicant's I-485 is approved.
還是會在review材料時，查詢到主申請人的最新狀態已經綠了，給approve?
