Well, Brazil screwed itself out of my visit (a real tragedy, I know

).
My call to the Consulte in NY confirmed that I would need a new visa. As I live in the Hartford, CT area, I would have to use a visa service and, as I am about to start a rotation at a client's site that will require an ID badge, I cannot spare my Passport at this time as it is my proof of citizenship.
I actually have my boarding pass for my SCL-GIG flight, but that will not fly as proof that I had entered on the Visa. I would have thought the fingerprint and photograph would have been retained, but apparently it is entirely for show.
Their Immigration Officer f-ed up and I refuse to pay the consequence of someone else's mistake.
