老師，我和我老婆實在過不下去了，我們結婚的時候都是 in good faith，但是後來發現她不誠實，她們家在很多問題的處理上更是極不負責任！結婚後多次重要的事情有意隱瞞，自己身體的事情，財產的事情，給別人作擔保書這麽大的事情居然都不和我先說一下，背著我就和別人簽字。現在我們已經沒有了相互信任，婚姻已經走到了盡頭。我們於去年初登記結婚，她是公民為我申請的conditional green card. 綠卡明年（2012）6月份到期。
請問，如果我們立即file divorce，我在美國的身份是否合法？ 如合法，合法至何時? 我最早什麽時候可以file I-751 based on termination of marriage?
-You can file it when you file divorce application or immediately after divorce to keep your legal status.
獲得綠卡批準的概率大概有多少？ 我需要提供什麽材料來申請I-751？ 是否必須請律師？費用大概如何？
-You had better find a lawyer to help you and the service fee depends on different lawyers. You may contact several lawyers to compare the costs. Normally about $3000 or little bid more is acceptable. This case is simple and any immigration lawyer can deal with.
