If I emigrate, what should I do with the old-age insurance I paid before? Should I continue to pay or stop?

according to China's social security policy, China's old-age insurance system guarantees the basic life of citizens with Chinese nationality after their statutory retirement; Immigrants who go abroad can apply for surrender and refund the individual payment part of their personal accounts with relevant certificates; If it is a country that has signed a social security agreement with China, it can continue the pension relationship (at present, China has only signed an agreement with Germany on labor and employment pension insurance). As you are immigrating to the United States, you can apply for surrender. In addition, China has recently promulgated the relevant pension insurance regulations for overseas Chinese to work and retire in China. If you want to return to work and retire in China in the future, you can also apply for it in China as a returned overseas Chinese.
