I just graduated with PhD degree in Mechanical Engineering. Thinking of applying green card for a while, but I just have one published journal paper. The other one is going to be published in two months. I have three conference published abstract. My group is the only one doing the research I am working now in USA. And currently I am a post-doctoral fellow in the same group as my PhD study. What is your suggestion on my case and anything I need to do in order to make the case strong ? Thanks in advance.
The information you provided are very general. It would be hard for us to judge based on this information. While it helps to have more publications, having few publications is not a disadvantage. You should ask your self the following questions
1. how important is the your research to the USA
2. is your work highly regarded by your well known researchers in your field
3. is there sustained interest for your work
Based on answers to these questions and the uscis criteria for eb1a and eb2-niw, you should be able to tell if you have a strong case.
