If you have an advanced degree(master/phd) and a few publications, you can try filing for EB2-NIW and I-485 concurrently. With that you can also apply for EAD and advance parole while your NIW and I-485 are being adjudicated. If you only have bachelors and no significant work experience(5 years or more) , this process is not going to work for you . Going back to school might be the best option.
