I guess your right but if he violates the terms of his visa can't they just expel him? Or are they afraid that the ridiculous system of monitoring imposed on the people over the past few decades won't be enough to find him. Can't they just pick him up when he hops out of the forest like a scared deer to visit this family that he is here to be around? The law just looks like a spoiled bully that is making up stupid rules because they're pissed because one of their subjects stood up for himself and said, enough is enough.
It's just easier and cheaper to refuse entry to risky people than to go chasing them down across the country when they run off. It sucks big time, but the US aren't the only ones who have these crazy immigration laws, although they do enforce them very strictly.
That, I'm sure, would be their argument. I would counter by saying that the difficulty or expense would be greatly reduced by the fact that this guy has been all over the media for at least five years and wouldn't be that hard to find. I think a every media outlet in the country would run the story and he would be found in a day. They could close his business and confiscate MemoryDealers in San Jose as a repayment for his debt to this poor nation who had to suffer through the ordeal of having a businessman running free (I couldn't even type that without laughing). You're right though, America enforces everything around the world "very strictly"
