I think it would be difficult for any attorney to answer this question. Based on the information you have given, I do not know for what benefit you qualify. Are you eligible to file the I-485 or I-131? I have no idea.
Separately, you do not have to hire an attorney for your paperwork. However, you have to bear the burden of making filing mistakes. Hypothetically, an applicant who proceeds without an attorney could face a situation where he initially qualifies for the I-131. If he makes filing mistakes, he will lose time because USCIS will send back an incorrectly filed application. By the time he figures the matter out, he may have lost the ability to qualify for the I-131. The point I am making is that you might consider having a consultation with an attorney before proceeding with this on your own.Ask a similar question
