Most of visitor wish to travel to CANADA etc, from USA, can they do that?
Yes you can. YOU have to have a VISA for this country as well. ALSO if you want to enter back to USA, you should have Multiple entry visa. So request for a multiple entry tourist VISA, and check for this option on your visa. Generally all 10yrs visa are multiple entry visa.And 6 months visas are single entry visa. If you get a 6 months, check whether its a Multiple entry visa or not.
