Purple Heart Army veteran self-deports after nearly 50 years in the U.S.

Earlier this month, immigration authorities gave Sae Joon Park an ultimatum: leave voluntarily or face detention and deportation.

Sae Joon Park left for South Korea on Monday. His removal order was the result of drug possession and bail jumping charges from over 15 years ago — offenses that, he said, stemmed from untreated PTSD.
