You need to prepare for anything your parents may throw your way. Dont bring up any of this on your own but be ready to give the facts if the question is asked.
Find the academic points of pride - admission% to med school, Fullbright or whatever, it doesn’t matter if they’ve not heard of it, just be ready to explain how solid, exceptional, high caliber it proves Wes to be. (Especially if the numbers are way better than UO).
Connect with the Interfaith association as well as the Muslim student association. If there’s an Imam on campus, email him. Ask about access to a mosque or worship services, anything that would reassure your parents on that front.
Email Housing and check ahead of time about substance-free floors so you can point that out if need be (ie., students who live there sign a contract that they won’t drink alcohol nor bring alcohol anywhere on the premises, if they don’t respect the contract they lose housing).
Keep all this info in your backpocket. Hopefully you won’t need to use it but this way you’ll be ready no matter what.
