Patient Q&A
Patient Q&A: If I renew my passport abroad, can I return to Shanghai on my current residence permit?
A Shanghai residence-permit FAQ says a traveler whose residence permit is still valid may return using the new passport together with the old passport that contains the permit, then apply within 10 days to transfer the permit details to the new passport.

Question: I may need a longer medical stay or follow-up period in Shanghai, but I also have to renew my passport in my home country. Can I come back without starting my residence-permit process from zero?
Answer: A Shanghai government FAQ says that if your residence permit remains valid, you should normally extend it before leaving when appropriate, renew your passport abroad, and then re-enter China using the new passport together with the valid residence permit in the old passport. The same guidance says you may apply within 10 days of return to transfer the residence permit to the new passport, using the passport-renewal certificate and the required supporting documents.
This is immigration guidance from an official Shanghai source, not individualized legal advice. Patients and families dealing with treatment timelines should still confirm their exact visa or permit category, supporting paperwork and local filing steps with the relevant exit-entry office before travel.
