Are my understandings correct?
A. I have been to Korea for two months. Does it mean I have this experience and have been there at least once(showing experience)
B. I have been in Korea for two months. Does it mean I went there two months ago and I am still in Japan now.(something started in the past ans has continued up to now)
C. I am what I am vs I am who I am. What's the difference in meaning? ?
