I entered the U.S on April 9, and they stamped my passport and visa with the admission stamp that says 'until - OCT 8', but that is 183 days and I thought the limit was 180 days.
Does that mean I can leave on October 8th if my stamped tourist visa says admitted until October 8th? Or do I have to before the 8th - and leave by October 7th? Or should I calculate 180 days from April 9 myself and leave then?
