Congratualtion Bengalitiger ! and best of luck to others who have applied or working for it.

I am also currently working to file EB2 NIW with the help of an attorney and now waiting for recommendation letters.
Here is what I have,

1. 17 peer reviewed journal publications (10 first author  including 1 invited paper and 1 review article & 7 second author), 2 under review (first author) and 2 will be submitted within 1 month
2. 12 non-refereed conference proceedings (8 first author, 4 second author)
3. Around 20 independent citations (since most of my publications are from either 2010 or 2011 so they are relatively new)
4. Around 50 conference presentaions (talks and posters)
5. Currently working on H1B Visa in a prestigeous medical school in a NIH funded project (cancer research)
6. Four invited lectures
7. Reviewed papers for 2 journals
8. Member of 2 scientific societies (easy one)
9. Have couple of awards from scientific societies for best presentaions/posters 

I talked with couple of attoneys and all of them are positive about my application. I am getting recommendation from 3 independent experts in my field and 2 from my circle. My lawyer says having too many recommendations will not make the application strong, 4-5 strong recommendation should be enough.

The only thing I am little bit concerned is about the number of independent citations that I have so far. Can somebody suggest me the experience if they have regarding the effect of low number of citaions in EB2 NIW application? And what is the application processing time these days for Texas service center? 

To be in safe side, I am not going for concurrent filing.
