I never thought about it, but I am sure hundreds of thousands have already moved to US on TN visa and they all lied about their intent especially Indians. But, I will try to stay away from TN visa (Given certain restrictions) and I will try L1 visa which is better any day.How're you going to demonstrate non-immigrant intent on a TN visa without strong ties to Canada? You'd likely need to own a house in Canada and show you intend to return back there.
