Canadian citizens in Asia travelling to US - Is a visa req'd

Could anyone confirm whether a Canadian citizen living in HK needing to travel to US for leisure and business need to get a visa?

Canadian travelling in USA don't need visa for touring but be careful if you are going to do business over there. They might ask you to fill a TN. By experience, if you are going to some meeting or training, just say that you are going for leisure, it will save you a lot of problem. The immigration officer can be a real pain in the cheek sometime. Thought, if you are going to work for some extend and will be paid by an americain company, take the time to fill a proper TN (NAFTA visa).

Hope it help,

Travel never business case by case!
