First, it is inevitable that foreigners will have enough education and experience to work there, and the hope is slim.
Second, South Korea is a country with a particularly strong sense of nationalism. Even if you enter, you will be excluded. If you have such good conditions, you can be a broker in your own country.
Third, living there is also very difficult. For example, artists who earn money for them suffer, and they are bound to be excluded. Must the landlord decide what kind of life he wants?
I still advise the landlord to think clearly and think clearly. His future is in his own hands, not to stop fighting. Fighting is not only to have enough patience and perseverance, but to be responsible for himself. Don't make yourself miserable. If you really have this goal, you should think about it. Think clearly, I believe you will be excellent in the future. It's gonna be great. Live high and belong to your own color. Come on!
