Sorry to hijack the thread, but could I just double check that with you Joe. I've currently got a multi entry non O based upon marriage. I'm planning to leave the country in another couple of weeks to get another 90 day stamp, based upon what you've said though I could actually just extend this (and all future) 90 day entries by a further 60 days, in effect giving me 150 days per entry. Is this correct ? For some reason I thought you could only do this once in the life of the visa and not for each 90 day entry.
