Generally one cannot "wait out" a lawsuit, if the defendant fails to assert that the jurisdiction the lawsuit was filed in is wrong, then the plaintiff will get a default judgment.
So, if you want to lawsuit moved to California, you may need to file Motion to Dismiss based on lack of jurisdiction or whatever the equivalent motion is in Virginia. Of course, if you signed some document that in the fine print says that Virginia is the proper venue in which to pursue all claims regarding the contract, then your attempt to move it to California may fail.
But, like I said, if you do nothing they will eventually get a default judgment against you. Then, they could probably file their Virginia judgment in California as a foreign judgment and pursue you for collection.
I don't know if this answered your question, and if not please let me know.
I hope this helps and a positive feedback is always appreciated if this was useful to you.
