green card (international insurance certificate for United Kingdom motorists)

I have a renewal acceptance letter for 24 months
If I don't receive my new card after 24 months
what will happen ？ I checked the USCIS website
. I got a message saying that my acceptance letter will expire next April but it is being processed so don't inquire until November.
I don't understand.
I wonder if I will receive a new application acceptance letter ？
Please let me know if you know anything about this.
