The F-1-D visa would allow individuals to stay in Korea for one year with the opportunity to extend for another year. Extension of stay would be handled by the local immigration office in South Korea.
To be eligible, you must be a remote worker employed by a foreign company, earning at least double South Korea's gross national income per capita from the previous year, which was around $64,000 for 2023.
Additionally, you must have worked in your current industry for at least one year, provide proof of health insurance, and have a clean criminal record. Accepted applicants can be accompanied by their spouse and children under 18 without additional visas.
Working hours
Korean Standard Time is +9 hours ahead of GMT, making it 7 hours ahead of CET during the summer months. In relative terms to other destinations in Asia, this is +2 hours on Bangkok and +1 on Kuala Lumpur.
I had already been working in the region for the three months previous, so it wasn't a huge change in working hours, but it's right at the edge of where you would class an acceptable working time whilst not impacting your daily schedule.
