回複：3 months, u can find it .

if you want come as business visitor under NAFTA, check this site: http://www.dfait-maeci.gc.ca/nafta-alena/temp_entry-en.asp; If you want to come as non-business visitor, since there is no I-94, I don't think there is a 3 months limit. It's up to INS interpretation of what is "temporary" and usually they treat stay less than 6 months as temporary. Can you please give the specific page that says Canadian citizens can only stay for 3 months?
