Not too my knowledge. Maybe you can Google it. Some lawyers will talk to you on the phone before you make an appointment to see if you "qualify" for a free consultation. In otherwords if you qualify for a benefit (married to U.S. citizen, have college degree and here legally, etc.). However, immigration law is by no means a simple area of law. Knowledge and experience count. Would you want to go to the cheapest doctor or the best? Its your life. How important is it to you to get unbiased and accurate information. Often times I charge a potential client a $100 consultation fee if its not obvious if they are eligible for a benefit. Often times thats all I will make on the case since I don't take peoples money if I cant help them. However, in the process I might suggest ways that they might become eligible in the future or what issues they will need to overcome. The worse thing you can do is be here illegally and file for a benefit for USCIS for which you are not entitled. Its like filing an application to be deported. Unfortunately, there are non-attorneys (and maybe even a few lawyers) who do so because of ignorance or greed. You get what you pay for.
