I have heard different people mention ITAR in the past. Does it only apply to formal instruction by for profit organizations? I foreign national visiting from overseas that I would like to take to the range (he has no firearms experience) and want to ensure that there are no issues with me giving him enough instruction for him to handle my firearms safely and obviously to hit the target (wouldn't be a fun experience if he didn't). Should I have any concerns as a private citizen doing this?
