I am planning on going to Canada as a tourist, I don't need a visa to go there, but I would love to visit USA as well since I'm there (for which I do need a visa).
How can I get a visa for USA this way? I know they require specific information about flight day, in which hotel I will stay etc. but I don't have such info as I would enter from Canada and I would be traveling around.
Also, will I be able to re enter to Canada once I go to the US? Will I be able to go back a second time to US if I re enter Canada?
EDIT: Polish citizen, living in Italy.
EDIT 2:I will add some more information that might influence the decision of letting me in the country. I don't have a job as I am taking a sort of gap year to travel, I have enough money to travel for a few months, and I have a gold Visa credit card
