Hi, I have just found out that on a tourist visa you can spend a maximum of 6months out of 12 in the US - I had wrongly assumed it was a calender year or tax year. I have just checked my days and found that I have gone over, 195 in a 12 month period. Is this checked by anyone? Does the day of arrival and departure count? I'm due to go again in September and am a bit concerned.
