Question:
We also suggest you read the post at this related link, which explains the relation green card and PhD. In other words one should not think that having a green card automatically entitles one for approval or denial. However, Phd’s have an advantage that they have a strong background to satisfy the USCIS requirements in the EB1A or EB2-NIW categories which allows them to self-petition for their green card.
This being said, we think you are the best judge to say if you have a good chance or not. The example packets simply assist you in this process. They explain the USCIS criteria and how one in a technical field would present a case to justify that they satisfy the criteria. You can structure your petition and evidence based on our example petition.
