L1 Blanket and I-140 case

[tarote]

My case is somewhat rare. I entreated the USA through a L1A Blanket Visa, and then after 6 months, my employer started the process of the I-140 and I-485 concurrently. During this time, I got my EAD approved and AP approved. EAD and AP expire on Nov 2012.

My L1 visa expired on December 2011. I continued working with EAD. My I-140 got denied last week (March 2012). Still waiting for the denial letter

In the meantime, I am going back to renew my L1A Blanket Visa next week. What type of questions should I get during the interview?

Thanks
