There are two major misconceptions that people facing deportation or removal proceedings have. They tend to think either that:
Both these ideas are, while understandable, misguided.
Immigration court proceedings are less formal than normal court proceedings. No jury will be present, less scripted legal language needs to be used, and everyone generally understands that the immigrant may not be familiar with American legal procedures. The immigration judge (IJ) is expected to act in an impartial manner. That means that he or she is not supposed to automatically side with the attorney who will be there for the Department of Homeland Security (DHS), but to consider both the DHS's arguments and the immigrant's before coming to a decision.
That is where the good news ends, however. The IJ is not going to think up legal arguments for you, nor help you present your case. The judge may not even know about circumstances in your case that might warrant a favorable decision or an exercise of discretion -- and, with a busy court docket, probably doesn't have the time to interview you and find out.
In short, if you show up in court with a charge of being removable -- perhaps because you are in the United States without authorization, or got convicted of a crime after obtaining your green card -- and you can't come up with any reason why you shouldn't be deported other than, "I work hard and have a family here," the judge will have no choice but to deport you. (This doesn't happen at the first, master calendar hearing, however. At that time, the judge will no doubt strongly urge you to get an attorney to help you figure out whether you have any defense against deportation. For an explanation of what happens at the various hearings, see "Overview of The Removal (Deportation) Hearings Process".)
An attorney will, before the hearing, spend the time to discover whether the DHS charge against you is correct, and whether any particular circumstances in your life would warrant defending your deportation. Because of complexities in the immigration laws, these possibilities may not be apparent to you, even after reading up on immigration law matters. The attorney may, for example:
Even if you believe that you might qualify for one of these defenses or applications, an attorney can help you make the strongest argument possible. The attorney will fill out any required forms, help prepare exhibits (documents backing up your statements), draft legal briefs arguing the case, and prepare you and any witnesses for the court hearing.
Even if the judge denies the case, having a solid amount of information on the record will make your chances of a positive decision on appeal much stronger. After all, this is your one and only chance to fully present your testimoney and legal arguments. Appeals do not give you a chance at a whole new review of your case -- they just focus on whether they immigration judge made the right decision given the information presented to him or her.
Unfortunately, immigrants are not eligible for free legal representation from the U.S. government. There are often ways to talk to an attorney at the first deportation hearing, but the immigrant must hire an attorney to represent them in subsequent hearings. But they should do their best to muster up enough money to pay a lawyer. Immigration lawyers tend not to charge as much per hour as, say, corporate attorneys. And low-cost services may be available from nonprofit (charitable) organizations that help immigrants and refugees.
