I met Cibele Jan 6, 2009, while she was visiting her daughters in the U.S. for the holidays. It was love at first sight for both of us. I have flown to Belo Horizonte about once a month for most of year 2009. We were fortunate! Unfortunately, I was being dragged through a prolonged and nasty divorce by a truly mean woman, and it wasn't final until Sept 28. I sent the I-129 app express mail on Oct 1, it was received on Oct 2, and we got the NOA1 dated Oct 5.
She decided to go on Tuesday, and I'll let you know. I read the regulations and it only requies a valid visa and your I-94, along with the other documents, like birth certificate, etc.
