The S2 visa (short-term private affairs visa) is issued by Chinese immigration authorities to foreign nationals who need to enter China for medical treatment or other private affairs. For healthcare purposes, it is the recommended visa option for patients whose treatment requires a stay of up to 180 days. It allows single, double, or multiple entries and can be extended up to 90 days twice within China.

Important distinction: The S2 visa is for short-term medical stays not exceeding 180 days. If your treatment will exceed 180 days, you will need an S1 visa (which converts to a residence permit) instead.

Visa-free caution: Many foreign nationals enter China visa-free (15/30 days) for what they believe is a quick medical checkup. However, treatment plans often change. Once your visa-free period expires, you cannot extend it. You must exit China or apply for an S2 visa conversion—but do not wait until the last day. Apply at least 7 days before your current stay expires.

Chinese immigration officers need to see a clear and logical chain: you have a legitimate medical condition, you can pay for the treatment, and you have proper accommodation. Prepare the following:

• Valid Passport – Must be valid for at least 6 months beyond your intended stay and contain at least 2 blank visa pages.
• Visa Application Form (COVA) – Complete online at consular.mfa.gov.cn/VISA/. Print and sign the confirmation page and application form.
• Passport Photo – One recent color photo (white background, 33mm x 48mm).
• Medical Diagnosis Certificate – Issued within the last 6 months from a recognized Grade A Level 3 (三甲) hospital or officially designated international medical facility in China. Attach an English translation if the original is in Chinese.
• Hospital Invitation Letter / Treatment Proof – Official letter from a recognized Chinese hospital stating: reason for treatment, estimated treatment duration, and confirmation that medical costs are covered or will be paid. (Our team can assist you in obtaining this document.)
• Proof of Sufficient Funds – Bank statements showing at least 10,000 USD (or equivalent) to cover medical expenses + living costs in China, or proof of international health insurance with adequate coverage.
• Temporary Accommodation Registration Form – For applicants already in China: within 24 hours of arrival you must register with the local police station (hotels/hospitals usually handle this). Without this form, your visa application will be rejected.

📌 Scenario 1 – Applying from outside China (recommended for planned treatments)

• Secure a hospital invitation letter from a recognized Chinese hospital.
• Complete the online visa application form (COVA).
• Submit your application in person at the nearest Chinese embassy or consulate in your home country.
• Provide biometric data (fingerprints) if required – note that applicants for single or double-entry short-stay visas (stay ≤180 days) may be exempt until December 31, 2025.
• Processing typically takes 4–7 business days (varies by embassy).

📌 Scenario 2 – Converting from visa‑free / tourist visa while already in China

• Do not wait until your visa-free period expires. Start the process at least 7 days before your current stay ends.
• Visit your local Entry‑Exit Administration Bureau (the immigration authority in the city where you are staying).
• Submit all the documents listed above – especially the hospital diagnosis and invitation letter.
• The immigration officer will assess your case. Approval is not guaranteed; a complete and professional documentation package significantly improves your chances.

• Do not use an M (business) visa for medical treatment. This constitutes visa misuse under Chinese law and can result in entry denial or deportation.
• S2 visas are generally for self‑funded or insurance‑covered treatment. Immigration officials want to see that you are not entering to claim public medical resources.
• Multiple‑entry S2 visas are available for patients who need to travel in and out of China during their treatment period.
• Extensions: Within China, S2 visa holders may apply for up to two extensions, each not exceeding 90 days. Total stay cannot exceed 180 days per entry unless converted to a different visa type.
• Bringing a family member? Spouses, parents, children, grandparents, and siblings may apply for an S2 visa as accompanying family members, provided they submit proof of family relationship.
