What should an international patient prepare before traveling?

International patients should obtain a valid medical visa (S visa) for China, which requires an invitation letter from the treating hospital. It is essential to bring complete medical records, including MRI scans, neurology reports, and prior treatment history, translated into Chinese if possible. Arranging an interpreter or using hospital-provided translation services is highly recommended for clear communication. Patients should also plan for a minimum stay of 4–6 weeks for initial treatment and arrange for follow-up care with their home neurologist, as stem cell therapy requires long-term monitoring.
