4.1 Pre-Arrival & Medical Visa (S2)

The Gateway: Securing Legal Entry for Treatment

The S2 (Private Affairs) Visa is the primary legal gateway for foreign patients seeking medical treatment in China for stays of 180 days or less. Unlike tourist visas, the S2 requires specific medical documentation and is issued specifically for the purpose of "medical treatment" or "accompanying a patient." The process is strict but straightforward if you follow the evidence-based protocol. Start this process at least 4-8 weeks before your intended travel date, as obtaining the hospital invitation letter and securing a visa appointment can be time-consuming.
