Hi Bala,

First of all, EB1B requires a sponsor, e.g., a research institution that gives you a permanent contract – you should talk to your employer about that. Speaking of EB1A, the most common (3 out of 10) criteria for your situation are:

1) Evidence that you have been asked to judge the work of others, either individually or on a panel
2) Evidence of your authorship of scholarly articles in professional or major trade publications or other major media
3) Evidence of your original scientific, scholarly, artistic, athletic, or business-related contributions of major significance to the field

Criteria #1 and #2 are satisfied. Now, criterion #3 might be less trivial to satisfy. You have to show that your contribution is of major significance. Smaller number of published papers is usually not a big problem as long as you have many citations demonstrating that your research is being used and, especially, if your are the first author of those papers. Looking at the recent trends, I would say that 50 citations could be an obstacle (too few). Maybe you have other ways to show the significance of your research (patents? products?). Also, consider the following additional criteria that you could possibly satisfy (we do not have enough information from your post to make an opinion on this):

4) Evidence of your performance of a leading or critical role in distinguished organizations
5) Evidence that you command a high salary or other significantly high remuneration in relation to others in the field
