Having your parents visit is a boundless experience for you and them. They can see and recognize the value of being engaged with another culture and educational space, where you see your home country from the outside and learn about it from another perspective.
One of the values that my father experienced was the professionalism of the Academia at the U of Minnesota, especially in the Department of Spanish & Portuguese. He noticed how the professors were reachable and open to talk with students and attendees, and how qualified the presenters were at the conference 'Power, Prestige & Periphery'. He constantly repeated that every single space at the U was charged with history and knowledge (he ended up attending two other conferences as well).
