oman, got my letter

I have received my official letter to go to Oman last week. I have sent the requested materials in to start the visa paperwork, but do not know when I will be there, in Victoria, on more vacation (I either need to use up my accrued time or cash it out), or possibly bouncing between districts that are nearby to help out. I will almost certianly not be home on or around Christmas as originally planned.
