回複：請問小白兔，pjiang，各位老師關於申請485和TN renew事

I strongly suggest that you don't apply for your I-485 until your 太太 get Green Card.You keep you TN status is better current time.If you 太太 fail to get Green Card,your family can continue to stay IN USA because of your TN visa.Otherwise your family might RISK leaving USA forever.
