Problem importing data - Character limit in the Description field for cases

Problem importing data - Character limit in the Description field for cases

In the cases field I was able to write a long description, even a few pages long 10,000 characters no problem in the description field. 

However, I tried to import a case with a long description about 10,000+ characters long using import (both migrate and the import command in the case view) and I was only able to import 3,000 characters out of the 10,000 long description field in my csv file.

Is there a fix for this? Or is this a limitation?

Please let me know how I can import various cases that have descriptions over 3,000 characters long.

Thank you.
