The Board held that grant of an INA 212(h) waiver for an offense listed under section 212(a)(2) would not remove the bar to section 240A(b) cancellation of removal for a non-permanent resident who has a conviction for a 212(a)(2) offense.
The Board reached this conclusion based on the statutory language of 240A(b), which requires that the noncitizen “has not been convicted of an offense under section 212(a)(2).” The Board determined that this language referred to actual convictions, not to whether an applicant was "inadmissible" for such a conviction. In contrast, other portions of the Act (including VAWA cancellation) refer to "inadmissibility" or "deportability." Since 212(h) waives only inadmissibility, but does not affect the existence of the conviction, it does not eliminate a conviction for purposes of eligibility for cancellation.
