I am a UK citizen visiting the USA on a 90 day Visa Waiver Program. My 90 days is ending shortly and I have been told that I can go to Canada for a visit and that when I return to the USA from Canada I will be starting a new 90 day visitors visa. Is this correct? I would hate to be stranded in Canada because my 90 days passed and I did not return to the UK. Any thoughts....PG
