The Board of Immigration Appeals (Board) has determined that a California conviction for assault with a deadly weapon or force likely to produce great bodily injury is categorically a crime involving moral turpitude (CIMT). The Board note that most general assault crimes are not CIMTs, but clarified that because the California statute required either the use of a deadly weapon or force likely to produce great bodily injury - both of which it considered to be aggravating factors - it was more reprehensible than a general assault. This more serious conduct counterbalanced the lack of any specific intent to cause harm in the statute.
