As a parent, Melvin’s concerns about college abroad speak to me more than the original poster’s arguments for attending the US school. It is also true that there may be more college options on the table once the RD decisions come out in the spring. So, OP, Melvin has given you some well thought out talking points.
In terms of my influence on my children’s college choice, I see it as my job to set them up for success. This might mean keeping a student closer to home who may need more support or encouraging a student to stretch by moving to a different part of the country or head abroad. It sounds like your parents want to nudge you out of your comfort zone. And, you want to stay in your comfort zone. Honestly, I’m pleased that my older is in college in a different part of the country because I think he’ll benefit from living outside Texas. I was not ready for him to live abroad partly because I like the support we can still more easily provide in the states. We can afford to fly him home for a long weekend if he needs that. And, he’s not learning how to live on his own while also learning how to function in a different country.
