How much do I need to earn for the F-1-D visa?
It depends on your age and where you will live. The base test is 1.5x per-capita GNI if you are 18 to 34, and 2x if you are 35 or over, measured against the Bank of Korea's published figure for the previous year. Staying in a non-capital region or a designated population-decline area lowers the requirement.
How long can I stay?
One year at a time, renewable up to a maximum of three years in total.
I qualified on the lower regional income threshold and now want to move to Seoul. What happens?
This is the trap worth knowing about. If you move to the capital region during your permitted stay after having had the income requirement relaxed, you are given six months, conditional on either meeting the capital-region income standard or relocating back outside it.
Can I switch to F-1-D while I am already in Korea?
Yes. Holders of the short-stay statuses B-1, B-2 and C-3 can change status in Korea, and holders of other statuses may also change if they meet the requirements.
Can I work for a Korean company on F-1-D?
No. The status is built around continuing employment with an overseas business or company performed remotely; it is not authorisation to enter the Korean labour market.
