Don't you have to show a birth cert to get a child INTO the US? What if they aren't given a birth certificate in Mexico?

We have taken her to Mexico before. They didn't look twice ate her when we came back across the border.

Of course, if we went to the consulate and told them our story, they might clue in and suddenly decide that she can't come back.

I hate to say it, but the first thing you need is a REALLY good immigration lawyer. One with clout. The bureaucracy simply can't deal with a case with unique facts -- it makes their poor widdle heads hurt, and it's easier just to say "no".

It's going to be expensive, but at this point with all the decisions already made by the agency, I don't see any alternative. They are going to be even more reluctant to undo what they have done and confess that they were wrong. They will probably have to be forced into it, either by a lawsuit or by serious influence from a senator or congressman.

You also need to make a total pest of yourself in your congressman's office. Just sending one letter is not going to get their attention - they get hundreds. (Don't contact the media until you have exhausted that avenue.)
