Just looking at the situation with Uzbek foreigners at Ajou University, the Overseas Korean visa should be abolished

People are doing a massive media play, acting like Koryo-in are descendants of independence activists.
If you look closely, there were many independence activists among the Joseon-jok as well.
Currently, 3rd generation Koryo-in have no intention of even learning Korean and just want to enjoy all sorts of benefits in Korea, a foreign country; personally, I view Koryo-in and Joseon-jok as being exactly the same.
There should be restrictions on issuing Overseas Korean visas starting from the 3rd generation; I don't understand why they keep issuing them to the 3rd and 4th generations.
