Congrats! I am still stuck in NC family-based

Please share more information of NC pending. I need to decide whether to renew EAD right now? It will be expired in Sept?

I submitted my application in July 2007 and interviewed in Nov. 2007, NC pending.

Infopass in March, nothing changed.

What you have done after NC pending? Just one time infopass? Any phone call? Do I need to call the local office or the officer who interviewed me?
