Asking a lawyer whether you need a lawyer for your asylum case is kind-of like asking a pastry chef whether you should have dessert. My answer: Of course you should hire a lawyer, and have a double helping of Windsor Torte while you’re at it.
A decent lawyer can help you prepare and present your case, and increase the likelihood of a successful outcome. However, there are some people who need a lawyer more than others, and if your resources are limited, you will have to decide how best to prioritize your needs.

So how do we know that a lawyer actually improves the chances for success? And who really needs a lawyer, anyway?
First, there has been at least one statistical analysis of how lawyers impact asylum cases, and the result is pretty definitive: Lawyers matter. A study of asylum decisions in Immigration Court by TRAC Immigration finds that, on average, asylum applicants with a lawyer win about 51.5% of their cases. Asylum applicants without a lawyer win only about 11% of their cases (the effect was even more disparate for “priority” cases involving women and children). That’s a big difference, but there are a few caveats to these numbers.
For one thing, the cases reviewed in the study were in court. Such cases are adversarial, and can be procedurally complex, as compared to cases before the Asylum Office. Thus, it is harder for an unrepresented applicant in court to win his case. Also, some applicants receive pro bono (free) legal assistance. However, it is more difficult to get a pro bono attorney if you have a weak or meritless case (or if you have criminal convictions). This creates a vicious cycle, where applicants with bad cases are less likely to receive legal representation, and I think it probably skews the statistics, making it appear that people without lawyers are more likely to lose their cases (since people with weak cases have a harder time finding legal representation). Even considering these factors, it does appear that competent representation makes it more likely that an applicant will be granted asylum.
But if you are like many asylum seekers, you have limited resources. Attorneys can be expensive, and pro bono representation can be difficult to secure. So who really needs an attorney, and who can get by without one?
If your case is before an Immigration Court, it is best to have a lawyer. Most judges will pressure you to get a lawyer, and they will usually give you an extension of time to find an attorney. Court cases are adversarial, which means that if the ICE attorney aggressively opposes relief, it can be very difficult—even for an applicant with a strong case—to effectively present his case, avoid any pitfalls, and obtain a grant.
For applicants whose cases are before the Asylum Office, the story is a bit less clear-cut. Asylum Office cases are (supposedly) non-adversarial. The procedural requirements are generally (but not always) less stringent. Many people prepare their cases and attend the asylum interview without the help of a lawyer (some use paid “translators,” with mixed degrees of success), and there are many examples of pro se (unrepresented) applicants who receive asylum. There are, however, some red flags, which, if present, militate in favor of hiring an attorney.
Asylum applications may be denied if they are not filed within one year of the alien’s arrival in the U.S. There are exceptions to this rule, but if you are filing for asylum more than a year after you’ve come to the United States, it is a good idea to have an attorney.
Asylum applications can also be denied if the applicant has been convicted of a crime, or if the applicant “persecuted” others in her home country (or elsewhere). If you’ve been convicted of a crime, or if you fall into a category where the U.S. government might suspect you of persecuting others (such as police officers, members of the military, members or supporters of armed groups), you should have a lawyer.
In addition, people who provided “material support” to terrorists are barred from asylum. Unfortunately, that covers a broad range of activities. So if you’ve given money or any type of support to a terrorist group—even if you did it under duress—you need a lawyer. Doctors who treated combatants fall into this category.
Other issues that might require the help of an attorney include travel back to the home country (especially after an instance of persecution), or living in a third country before coming to the United States.
Finally, to win asylum, the applicant must show that she faces persecution “on account of” race, religion, nationality, political opinion or particular social group. If you do not obviously fit into one of these categories, it is helpful to have an attorney, who can make a legal argument that your case falls into a protected category, and that you are thus eligible for asylum.
Even if there are no obvious issues in your case, a lawyer’s advice can be helpful. Sometimes, there are problems in a case that are not apparent until a lawyer reviews it. You are far better off identifying and addressing such issues before they become a problem. For those who cannot afford an attorney, or who choose to do their cases pro se, it is possible to win. But some cases are more difficult to win than others, and-especially for these problem cases—the help of a competent attorney can make all the difference.
