What do the initials BC mean that were placed by US Immigration when they stamped my entry to the USA? I entered through the port of Miami legally.

Almost certainly a B2/B1 stamp that looks like a C.
For example in a previous question (I have a B2 visa for the US, but I was admitted under the Visa Waiver Program. Now my ESTA will expire before I leave the US. What should I do?) you can see a B2 stamp where the '2' looks like a 'C' at first glance.
