Please see the D.C. Bar Reciprocity page to view the requirements for Admission on Motion; the D.C. Pro Hac Vice page to view the requirements for admission to a particular proceeding; and the D.C. Multijurisdictional Practice Rules (MJP) for legal practices that are excluded from the unauthorized practice of law.
