Is it possible to apply for an F-4 visa in Seoul?

Hello! I was looking into the F-4 visa and considering applying for it, but I'm worried because I won't have time to apply at the local embassy before leaving the country. Therefore, I plan to first go to Seoul on a tourist visa and stay there for a few months. During that time, can I apply for the F-4 visa in Seoul? I would appreciate it if anyone who has experience or advice on applying for the F-4 visa in Seoul could share their insights.
