Serious. Prostitution-related offenses are classified by federal immigration authorities as crimes involving moral turpitude (CIMTs) and, in some configurations, as aggravated felonies. Consequences can include denial of naturalization, denial of visa renewal, denial of green card applications, and removal (deportation) proceedings - even for people who have been lawful permanent residents for decades. Non-citizens should not plead to any prostitution-related charge without a lawyer who has reviewed the immigration consequences. The exact wording of the plea matters enormously: a plea that looks equivalent to the criminal case may have dramatically different immigration outcomes. Bank & Munns coordinates with immigration counsel when needed to ensure the plea does not close doors the client cannot reopen.
