My credentials for NIW:
1 I am a postdoctoral fellow with M.D and Ph.d degrees in a top 3 University.
Fine. The field is more important than the university of how many degrees you have.
2 two publications in top journals and five papers in foreign journals,and two chapters
More is better from this. Are the articles in field of national interest? Make sure your articles in journals with high impact factor. While many officers look at this positively, the citations are critical. Any scientist can produce papers, but few can get cited. Collect your citation index.
3 two memberships
While this is good, make sure they are not those you pay-and-you-are-in. Are these memebrships based on your scientific quality?
4 ten strong recommendation letters, 2 from big guy, 1 from FDA, 1 from a congressman
The number is very good. Do these letters reflect your qualifications? Is the congressman an expert in your field?
5 several adwards in foreign country
Based on what you were able to get the awards? Please show them the selection rules......... MAny officers issue RFE for awards from foriegn countries. The reason is clear, some officers believe we just have printer at home for such awards. While this is unfair bur make sure that your awards well-explained to the officers.
6 major media intentions
This is very good. This part should talk about you NOT the field of research in general.
Are you a referee in any journal? Do you have a patent? Make sure your field is in the national interest scope.
Good luck
Any suggestions will be welcome.
