I obtained a working visa for Canada for two years to start between April 2015 and April 2016. I am planning to work in Montreal.
I am presently visiting friends in Vermont, and have been here 60 days.
I realize that simply entering Canada will not affect my ESTA, but I wonder whether beginning my work visa in Canada will this reset my ESTA, thus allowing me to visit my friend time to time from Canada.
Also, if I leave the US to go to Canada one month before the end of my ESTA, would I be able to come back to use these 30 days another time during the year?
