請教各位老師大俠：我是綠卡主申請人。老公拿綠卡前半年因家事就回國了。後來有了綠卡，也還在國內工作。但總能每2一3個月，多則5個月回美國1一2個星期。現已拿綠卡2年半。今天入海關時，入了小黑屋，移民官說要麽放棄綠卡，要麽申請白皮書，放行。請問
（1）因沒有準備可以下次來再申請嗎？
-He has to apply for the reentry permit before he leaves US again, otherwise his green card will be taken away when he comes back and he will not be allowed to enter US. Please remember the green card is for him to live US permanently, not just use it as border-crossing card.
（2）可以這次先遞表就回中國，等打指紋時再來美國打嗎？
-Fine if he has to leave urgently.
來時帶著家人住院證明或公司開的不工作經濟損失大的證明？
（3）因老公常年在國內，孩子又小，我最近也回國待了起來，但也沒申請白皮書。老公申請白皮書或者綠卡收回，會對我的綠卡／將來公民申請有影響嗎？
-irrelevant.
我是主申請人。已住夠2年。未來也能保證每半年來美一次。
-If you do the same way as your spouse, you will have the same problem as his.
