I am a European citizen with Spanish passport and therefore I needed no visa for tourism in Japan. I was given a 90 day period (Sep 16 to max. Dec 15) and within that period I must go to the US for an interview (Nov 30 to Dec 5)
My flight back home to Spain is on Dec 14 so it is not an extension of my original period what I am after. I just need to interrupt my holiday for this specific thing and I am afraid of not being able to re-enter, join my (also Spanish) wife again and finish our vacation normally.
Is there any objective information about the regulations regarding re-entry for this type of permit?
