What are your plans now?

I switched from an I-800 to an I-600. I spoke with numerous people at USCIS and there is no credit whatsoever. You have to start over completely. They even make you do your biometrics (fingerprinting) again. Not one penny saved. The only upside to it all is that I got my approval in 3 or 4 days. I am guessing because we were already approved, they just rubber stamped it...after cashing our check of course.
