This bill adds drunk or impaired driving to the list of reasons someone who isn't a U.S. citizen can be turned away at the border or removed from the country. For people trying to enter the U.S., simply admitting to having driven drunk in the past—even without a conviction—could be enough to block entry. For non-citizens already living in the U.S., an actual conviction for driving while intoxicated or impaired would be grounds for deportation.
