not sure as I've never done it on this DTV Visa but I know people have done it with out issue but there again certain people have issues on land boarders ie Lao & Cambodia etc..
As far as I know the wording says has to leave the country within 180 days it doesn't specify the time length etc...
Have to wait and see but I've already seen posts and know people that have easily gotten through without having to "Oil / Grease" the well oiled money machine ...
