[mma.chris]

I am moving out of state for a job opportunity and to be with my fiance, I have been subpoena and have shown up for every court appearance. They have changed the date and time to a month later, I can't put my job on hold anymore nor do i want to. I want to be there for this, but financial starting a new job, getting married has been put on hold for months cause they keep changing the date. What can I do so i honor the subpoena and not have to fly back and forth due to my current financial situation i just can't afford it. Can i give my testimony here where i live prior to leaving or can I give via satellite, phone or what? Please help me I am leaving February 3rd and want to do what is best.
