My friend is currently on a visitor visa in the US. He's visiting his brother who's a US citizen. This same friend has another brother whom is an accepted convention refugee in Canada. They were wondering whether the American brother can drive his brother through the us border to make a claim at the Canadian border. Would this create any issues for the American brother, would the American brother be allowed into Canada with the refugee claimant brother? Would it create issues for him when crossing into Canada in the future?
