3. 如果現在我申請和LG離婚的話,對正式綠卡的批準有什麽影響?
-Yes. If you divorce now, your I-751 filing will be invalid and you need to file a waiver by yourself. You had better talk to a lawyer about it if you want to divorce now. In my opinion, you had better not divorce until you get the permanent green card. As for the tax return, you had better file a joint return with your spouse at this point if you want to get the permanent GC before you divorce. Anyway, talk to a lawyer.
