Criminal defense attorneys are duty-bound to inform clients of the risk of deportation under three circumstances. First, where the law is unambiguous, attorneys must advise their criminal clients that deportation "will" result from a conviction. Second, where the immigration consequences of a conviction are unclear or uncertain, attorneys must advise that deportation "may" result. Finally, attorneys must give their clients some advice about deportation—counsel cannot remain silent about immigration consequences. Decided March 31, 2010 (argued October 13, 2009).

Commonwealth of Kentucky, 559 U.S. 356 (2010), is a case in which the United States Supreme Court decided that criminal defense attorneys must advise noncitizen clients about the deportation risks of a guilty plea.
