AR,
Yes, a "green card" means the "right to live and work in the US." There are visas available that would let you go to flight school, then say on as an instructor for a year. "I would like to be an airline pilot for a US carrier" is not likely a be an effective route to permanent resident.
However, you'd probably have a decent chance if a Korean medical degree is recognized/recognizable in the US. As a legal resident you would be free to pursue whatever free time activities - such as flight training - that you would like to do. You could even work part time as a flight instructor.
You could even be a full time instructor and a part time doc...
