Pjiang and 883211 please help!

NIW I-140 submitted on Feb 2007, approved on April 2008. I-485 submitted on 08/2007, still pending.

 

Now I am preparing the EB1a package, besides recommendation letters and personal statement, what else do I need for the application package? how should I submit the package? Could you please provide mail address and webpage for E-submission?

 

No matter what happens to EB1a application, it should not affect the approved NIW I-140. Am I correct?
