how long your allowed to in the usa

For that really don't know about the us laws.

I stayed in the usa for 6 months on a passport I learned something by reading the usa law,page after your stay in the us u always don't need to have visa to stay that long in the us.just have to be honest with what they ask u don't lie it will end u going back home.they always little things u have to watch out as well don't get sick they will not allow u entry into the usa or back in canada.be honest were u are going and were u be staying and u shouldn't have any problems.there more I'm not go and on.
