Korean teenagers growing up in the United States, how should they choose their nationality?

Hello, I am 18 years old and soon to be 19, a South Korean national with a U.S. green card. I moved to the U.S. when I was 8 years old and have grown up here ever since. I am currently in my senior year of high school and preparing for college. My current dilemma revolves around maintaining my South Korean nationality, military service, and where to plan my future. My parents believe that staying in the U.S. to obtain citizenship and build a career is the best option. They worry that if I return to Korea, I might regret it or miss out on opportunities. However, I feel a sense of love and responsibility towards Korea, and I am positively considering military service. All my family lives in Korea, and my parents also think they might have to return to Korea someday. In this situation, I am confused about where my "home" is. Maintaining my South Korean nationality is important to my identity, but I am struggling with where to plan my future. I would like to hear the experiences or advice of others who are also grappling with similar issues between two countries. How can I make the most of the opportunities in both countries?
