What is F-1-3?
Granted to someone who is a cohabiting dependent ('동거인') of a person holding 외교(A-1) through 협정(A-3) status, but who is not counted within that sponsor's registered household unit (세대). It is issued abroad as a visa (not a domestic status-change), with a capped short stay period.
Is F-1-3 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-1-3 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.
