Is my 10 year S2 China VISA still valid?
I am a US citizen carrying two passports. One that expired with my China 10 year S2 VISA in it and one that is valid that now has a 30 day extension VISA that expired. My 10 year VISA will not expire until 2025 and has a 90 day duration of stay. I was in China and needed to get a extension due to the inability to leave the country because of the virus. My 90 day duration of each stay was up and I could not leave. After one 30 day extension, that is in my passport without my S2 VISA, I was able to find a flight back to the USA. My 10 year China S2 VISA was never stamped with ‘cancelled’ like my previous visas. My question is can I still use my 10 year S2 VISA to enter China when the borders open? I have belongings there that need to be collected.
If I get a new clean passport without the 30 day extension visa in it would my 10 year S2 VISA in my other passport still pass at the border?
Thanks for your expertise!
