What is F-2-6?
A 거주(F-2) residence subtype formerly used for skilled foreign workers ('숙련기능 거주인력'). The manual states plainly that this status was abolished, with existing/pending cases folded into the separate '장기거주' (long-term residence) category rather than continuing under F-2-6.
Is F-2-6 a work visa?
Not by default. Check what this status authorises before taking any employment — several codes in this family permit none, and some require permission obtained in advance.
How long is F-2-6 granted for?
Stay periods for these codes sit in the manual's tables, and several are tied to a principal holder's remaining period rather than a fixed term. The digits are not reproduced here; confirm them against the current manual.
