Be careful
The goal of NIW and EA petitions is to prove that you are contributing to major scientific discovery AT THE PRESENT TIME. They don't want to hear about your potential, about future impact of your work on others' research, about how you'll be among the top scientists in the future. They want to hear that you are already a major scientist, that your work is widely used and regarded, that you've already reached the top of the your profession.
Of course, only a few of us really, truly qualify for these kinds of benchmarks. However, the point is to present your case in terms of what you're CURRENTLY worth, not what you'll be worth five, ten years from now.
Not having any citations to your work is a sure red flag; unless you're doing cutting edge research and can prove your research's ready impact on others, I will personally wait till I get a few citations before I file.
GOOD LUCK!
