This is true, but because xeta has been in NA for so long he might be considered an NA player, so they might be able to get one more Korean player if they want to stay in NA.
Not all all. To get regional residency (NA, EU, KR, etc...), u need to have played 3 years of the last 4 years in the region when u are a foreigner. For instance, xeta will have NA residency in January 2024.
yeah but how long was he in KR for? if it was less than a year then he actually could count as NA player if his time in NA csgo counts towards this 4 year thing.
