回複:請教法居士!何時遞交配偶I-485?
You can file your hu*****and's I485 before or after your I485 get approved as long as you got married before your I485 approved. It is professional lawyer's opinion since I have a friend who is in same situation as you.
Maybe it is better for you to file your hu*****and's I485 after your I140 get approved. see following link(FAQ in張哲瑞聯合律師事務所 web)
