Narrative:

Our mq-9 predator aircraft was cleared to operate in ATC blocks M1; M2 and M3 from FL200 to FL220. The aircraft was piloted by myself as a pilot under instruction. Training was being conducted by the instructor pilot during the transit east through our assigned airspace. The aircraft continued east from block M3 to M4 and the aircrew discussed that we had not yet asked for this block. Minneapolis center was immediately contacted to obtain clearance from blocks M1; 2; 3 to blocks M4; 5 and 6. ATC noted that we were in block M4 and verified that our current clearance was for blocks M1-3 and then gave us clearance to operate in blocks M4-6.
