The Board of Immigration Appeals has determined that the language of a state conviction and an asserted ground of deportability (in this case, a controlled substance violation) should be compared as they were written at the time of the non-citizen’s conviction. Thus, any post-conviction revisions to the Controlled Substance Act were not relevant to whether the non-citizen was deportable.
