Just to add a little "Sadness" to the answer. You might consider your son/daughter to be a college student, but they are 100% in the "Military".
Oh, now you've touched on something!
My 1/c summer at CGA I was assigned to a 210' cutter (USCGC ACTIVE) out of Port Angeles, WA. I was with the cutter for 10 weeks with a classmate of mine (good guy).
Well, at some point my parents decided to come visit us from Tennessee. There was a marathon and my dad was going to run the half. While they were there we (my family) decided to go to Victoria, BC, just across the straits. I had already been to Victoria with my classmate earlier in the summer.
We headed over via ferry and went through Canadian customs.
When asked if we had been to Victoria before my parents answered no, and I said yes. I was then asked when I had last visited. I told him. I was asked why I was in the area..... and that's where it got interesting.....
Customs officer: Why were you in the area?
LITS: I'm in the military and on a ship in Port Angeles for the summer.
Mother: No he's not. He's a student.
That was followed by a fairly clear glare from LITS
Customs officer: Do you want to get your story straight?
LITS: I'm a cadet in the U.S. Coast Guard and I am stationed on a ship in Port Angeles for the summer.
At the border of a foreign country is not the spot you want your mother to find out you're not only a student but a member of the military. I'll just say the conversation leaving the customs area between my mother, my father and me was interesting....
