Are you experienced in advising students in the area of travel necessities such as insurance and visas?

Tell the interviewer about your experience in this area, and if you don't have any, show them that you are willing to learn.

"I don't have much experience in consulting with students on travel insurance and visas, but I've travelled myself so I've had to look up information for several countries and am confident I'd be able to handle that on the job."
