My lawyer filed NIW I140 for me, later I found a critical mistake in the application package which maybe lead to deny. So my lawyer sent a withdrawal letter to NSC March 12. Till now, the case status didn't change. It is almost 3 weeks already. My lawyer insisted to have the withdrawal letter first, then he can refile NIW I-140 case. I am vey worried about my status. I just begun my sixth year H1B. If I cannot refile my case soon, I am worried about I can get the I-140 approval before my H1B expires. My question is:

1 Can I refile my case before I recieve the withdrawal letter, even now before the older case status changes to withdraw?

2 How soon I can recieve the withdrawal notice?

3 Where can I contact to complain so that I can get the notice sooner?

Thanks for your attention and helps.
