If I was in your situation, this is what I would consider:
1. Master Calendar hearing is for the judge to see you, read the 'charges' against you: That you are in the country illegally, but since you are claiming asylum, you can stay. Come back on mm/dd/yyyy for arguments about why you are qualified, or deserve asylum. The judge will also call out your name, make sure everything is good. While going to the master calendar hearing with a lawyer is recommended, when you go there without a lawyer it doesn't change anything technically. Of course if you can afford a lawyer, bring them to the MCH. The MCH is just an administrative thing. At this stage, I had no money, so even if the lawyer was asking me to give him $200, I couldn't.
2. Individual hearing - After the MCH, the real deal begins. Since most people are getting their hearings 1 or 2 or 3 years out, I would work with pro-bono lawyers to prepare my case. The pro-bono lawyers, they are not there to convince the judge about your case, they are only there to help you:
a) Format the case - present your case in a manner the judge expects. This is a court proceeding, so there are expectations on how a case is presented
b) They help you source and prepare exhibits - Freedom of Infor Request (to show you have no criminal record); doctor evaluation for injuries from torture, trauma, etc. Based on your case, the pro-bono lawyers will help you get all all this information
c) They will submit everything to the clerk of court.
d) They will also get the prosecution's record against you - where the govt. says you must be denied asylum and be deported.
e) Some pro-bono lawyers would allow you to use their office resources - computers, internet, fax, phones, the address etc. These items seem basic, but for most asylee applicants who are not working, who have just come into the country, these are hard to come by etc.
So, I would focus on finding pro-bono lawyer to help with the case, not stress about paying the lawyer. How:
a) Most law schools have asylum help clinics
b) All law firms have pro-bono lawyers. Your case doesn't require the lawyer to spend more than 5 hrs a month working on it, so most lawyers are happy to help. Besides, it makes them feel better. So, reach out to the law firms, big and small
c) There are many not-for profit organizations who run programs to help asylees. They have lawyers who can help you.
