On March 22, 2025, the Trump administration issued a memo specifically targeting immigration practitioners and making baseless accusations about fraud occurring within immigration legal practice. In this memo, the president directs the attorney general and the secretary of homeland security to prioritize enforcement of federal regulations governing attorney conduct and discipline. While this directive should not deter practitioners from advocating zealously on behalf of their clients, practitioners should be aware of and understand the disciplinary process in the unfortunate event that they are accused of misconduct. This practice advisory explains the professional conduct rules for immigration practitioners and the rules governing the corresponding disciplinary procedures.
