What should an international patient prepare before traveling?

International patients should obtain a valid visa for medical travel, typically a medical visa (S visa) with an invitation letter from the hospital. It is essential to arrange for a professional medical interpreter, as most hospital staff primarily speak Mandarin. Additionally, bring all relevant medical records, including echocardiograms and genetic test results, and plan for at least 3 to 4 weeks in China to cover treatment and initial recovery.
