Most people would apply for the extension at least 4to 6 months before expiration. Don't wait till the last minutes if you can. Once you get a receipt date, you are coverd for 240 days from the expiration date. I doubt you would need to apply for a new one after it is expired, but i don't know for sure.

最主要是如果不是timely filed for extension的话就没有那240天了 必须拿到approval才能工作 而且有gap可能就让申请人离境去签证了,比较麻烦
