A wavier would have been required
这个wavier是怎么回事呀，我的律师从来没提过，并且移民局也从来没有说过这个。
-This means you was not qualified for I-485 filing to get the green card because you were a Chinese Communist Party member and you did not explained it at that time, so you needed the waiver before you filed I-485.
Now, you need to show your evidences as you mentioned to the IO during the hearing for your N-400 to justifying you did not hide anything.
