So I do not count only days I am on OPT before my visa change to H1B for the SPT? And then count the days after my H1B comes into effect for the SPT (which I pass)? Or is it because I am present on Jan 1st 2016. In other words, if I am out of the country from Jan 1st 2016 to Jan 5th 2016, then I will be considered dual status? Many thanks.
