Is it ok to travel to Tunisia for a week's holiday after my interview before I leave for America for good.
Does anyone know, I doubt it would be a problem as I don't need a visa to go there.
Any help would be great, you know how this visa lark makes you panic about anything!!!

No problem! As long as you enter the USA before your visa expires, you're free to travel around the world beforehand.
