香港人係加拿大讀書去美國點搞簽證?

What you really need is your Canadian passport.

Canadian Passport holders can enjoy 6-months for visa-free travel (Additional time may be granted if it is covered by NAFTA. In that case, a visa may be needed).

你真係識講笑, 既然你係加拿大公民; 只要申請個加拿大護照咪就咁行過去美國囉.

簡單方法是申請一個加拿大護照, 因為你說你有加拿大國籍 . 可以去7-11或在加拿大的郵局拿申請表. 使用加拿大護照去美國.
