Quoting
Mr. Knowitall
A court of one state can't "change venue" to a different state. It sounds like the creditor sued in the proper state and court, and you have admitted to the court that Arizona is your state of domicile through April 8, so I'm not seeing a reason why the court would find that it lacks jurisdiction or is the wrong venue. Depending upon the court's schedule and policies, the availability of opposing counsel, and what type of hearing we're talking about, perhaps you'll be lucky and have things wrapped up before you move.
Start researching the summary disposition process for the court, and consider bringing a motion for summary disposition that would resolve the case in advance of trial. For example, if discovery is permitted by your court, seek the documents that would substantiate the collector's right to enforce the debt and, should they be unable to produce it, use that failure as a basis for arguing that they lack standing. (In some courts, such as small claims court or municipal courts, some states don't allow discovery, limit discovery, or permit discovery only by leave of the court.)
