How do I navigate visa requirements for medical travel to Korea?

What are the specific visa requirements and application processes for foreigners seeking medical treatment in South Korea, and what steps should I take to ensure a smooth and hassle-free medical travel experience?

When my cousin traveled to Korea for plastic surgery, getting the medical visa was easier than expected. For most procedures, including cosmetic surgery, a C-3-3 medical visa is needed, allowing up to 90 days of stay. The main requirements are a treatment plan and an invitation letter from a certified clinic. Human Plastic Surgery in Seoul helped with everything, including the visa paperwork.
