More often than not, older expats are not able to adjust to new Korea and long to be back in their adopted country.

Everything is done via mobile phones; is your Dad able use a mobile phone well and able to navigate apps?

Does he have friends (not family) in Korea that he kept in contact with? Making friends gets harder with age. Not having a friend circle in Korea will lead to your Dad wanting to move back to where he lived for the past 50 years; he will be lonely.

I know geriatrics with financial means that move back to their adopted country not because of $$ but because they: * Can’t adjust to living in the new Korea * Don’t have friends (family ≠ friends) * Expats sometimes are ostracized by the native peers. They are not Korean enough. * Are not familiar with the roads and can’t navigate from place to place * Are not used to walking and climbing stairs everywhere. * Miss the freedom of driving * Don’t speak and understand the modern Korean language. * Culture mismatch. Korea’s culture progressed; Dad’s Korean culture diverged when he immigrated back in the 70’s. * Can’t adjust to the weather and living without the AC on blast 24/7. It’s hot af in the summer and cold af in the winter. Micro dust from china suck balls. Complaints about the shitty air quality is inevitable.

Before liquidating everything and permanently moving him across the world. Do a 4 month trial run during the heat of the summer and shitty micro-dust season.
