2 years is huge. Being legitimately there is huge. 1. Right now you can be a "tourist" and have to leave/re-enter every 3 months. So things like renting an apartment for a year become out of the question, since SK could arbitrarily not let you re-enter. So you're stuck with the whims of hostel / airbnb owners. 2. Being a "tourist", you can't open a bank account or get a legit phone number. So you can't verify on Naver, which means you can't do things like book appointments for businesses that use Naver (which a lot of them do). You can't use KakaoPay without it either, so exchanging money with South Koreans means resorting to bitcoin which is just tedious.
