Public interest law can be pursued through various means, including providing direct legal services to individuals who cannot afford private representation, engaging in impact litigation, advocating for policy changes, and educating the public about legal rights. Unlike private practice, public interest law offers lawyers the opportunity to make a significant societal impact through working on issues including civil rights, environmental law, justice reform, human rights, disability issues, domestic violence, consumer protection, criminal law, or immigration.

Public interest law is often practiced by non-profit organizations, government agencies, and legal aid societies. Lawyers in this field may also engage in pro bono work, providing free legal services to those who cannot afford them. Law students can gain valuable experience through internships, externships, and volunteer work during their time at law school.
