How do I import an MKV file into Premiere Pro CS6?
Welcome to the forum.
You can't do that. You'll have to convert it into a different format first. If you search the forum you'll find several discussions about MKV files and Premiere Pro.

For a specific MKV to h.264 convert I recently discovered a free tool for Windows and Mac called MP4Tools. It works wonders and is fast. I believe there is another called AVITools that converts MKV to AVI, but I don't necessarily see a need for AVI personally. MP4Tools will create the video in an m4v wrapper, but I haven't had any issue using that in premiere or converting it to a more uncompressed format.
