I am engaged to some one in the navy when we get married will hes 2 year unaccompanied tour be able to change to accompanied.He is in Japan/sea duty.Could he extend for another year or so ,so that this could be accompanied.
Not up on Navy tours, but you need to ask if accompanied is possible at that base. If it is, they could tack 1 extra year onto his tour once he marries. Its best for him to speak to someone like his supervisor and find out the correct people to ask.\nI know with Air Force, if I wanted to accompany my husband and it was allowed, they'd just tack an extra year onto his orders and it wouldn't be a big deal. But it all depends on if they are letting family go with him.
The instructions for the form do allow for some leeway in the "how long do you plan to stay" question.  Still, you should call the office at your school that produced your I-20 form to make sure that they didn't make an error.  As you read, the I-20 specifically asks about the "normal" term of study.  If your school feels that 36 months is normal, put that on your DS 156.  But if you call them and they say that they made an error (which seems unlikely), then you should put whatever they tell you is the correct term of study.
