Let me introduce my self.

Hi, my name is Hye-Jin Jeong, and my English name is Genie. I live in Korea and want to live in foreign nations countries. I want to be a fluent English speaker. My hobby is singing and listening to music, and I'm a leader of a hiphop circle in my school. Although my English is poor, I want to make foreigner friends in here. Thank you.

Notes: I replaced "nations" with "countries" because we would more normally use "countries" in this case.

Your English is good.
