When we got three days notice to be there or else, we did not know about Golden Rule or any other agency specializing in short-notice travel. Our lawyer suggested:
http://www.federaltravel.com/
Not the best web site in the world, but the man worked magic to get us there a day early.
And when we had to stay longer because of the inevitable bureaucratic mess (really, is this a way some countries increase revenue from visitors?), he waved his wand again to make changes with fees, well not waived, but tolerable.
