Can Shenzhen social security second file take effect immediately?

Hello, dear. I'm glad to answer your question. Social security shifts can only be changed once a year. If it was changed that year, it will take effect immediately. You can choose the gear you want to change when you pay the fee every year, but you only have one chance every year. As long as it was changed that year, it is not allowed to change it again. I hope I can help you.
