My daughter didn’t visit any of her OOS schools until after she had her acceptances. She showed interest by – as others suggested – writing about specific departments and even professors she was interested in studying with. She also met with the campus representatives at a local college fair. She made it clear to the rep for her #1 school that she was VERY interested and likely would matriculate there if she got in with the average FA package. She applied early, got in, and got better-than-expected FA. That’s when we flew in for a campus visit.
