What visa options allow a Mexican chef to work or open a restaurant in South Korea?

I’m a Mexican national who’s been running a popular taco stand for the past 2½ years, and now I’m aiming to take my culinary career to South Korea. Korea’s vibrant food scene and the rise of globally recognized chefs there inspire me to gain professional kitchen experience and eventually launch my own concept. Could anyone outline the main visa categories that cover culinary work or restaurant entrepreneurship (e.g., E‑7‑3, D‑8, or any newcomer programs)? I’m especially curious about typical eligibility requirements—formal culinary education, minimum years of experience, investment capital, Korean‑language level, etc. Also, are industry sponsorships or government‑backed incubation schemes realistic paths for a small‑business owner like me? Any insights on processing times, common pitfalls, or success stories from foreign chefs would be greatly appreciated. Thanks in advance!
