Do I have apply for exit permit if I want to go overseas

Okay, I may be going to Japan for a school trip on the 15th of March. But I'm not sure whether I have to apply for an exit permit via mindef because I'm over 16 =_=. It's not even stated on the damn website whether I have to do it or not (SG portals are SOOOOOO useful)

Anyone cares to enlighten me for that? Hope for answers before 11th, that's when I have to submit my forms.

i think only if you going oversea more than 1 months, then you have to apply exit permit. Have you enlisted?? or you have a deferment letter???

11 is today =D

hmm exit permit arr.. for me i think if overseas 3mths are more than need i think if i can recall correctly..if not send a e-notification.
call mindef best haha!
