Has anyone ever had their fiancé(e) dutifully abide by the requirement to "do not open" their visa package, only to have the airline itself do the dishonors at boarding? Did they show up at the border anyway, and were they paroled or denied entry? If denied entry, did that become a black mark on their history barring them from future entry? Were they charged for the involuntary return flight back home, which the airline had largely caused?
That is, in a nutshell, my situation now. In more detail, my Brazilian fiancée and her daughter were supposed to arrive last night in Miami, to enter on their respective K-1 and K2 visas. I flew to Miami yesterday to meet them, but upon landing I learned they had been denied boarding because Latam, the airline, wanted proof she had the legal right to take her daughter outside the country. She was told to go to the federal police station in Fortaleza to obtain that authorization, which would not be doable in time to actually board yesterday's flight. So at significant expense, we booked another ticket for the next such flight on Monday. The federal police did indeed give her the authorization LatAm had required, but not without first opening the "do not open" packet to see if that foreign travel authorization document was included within it (it was). So now she's booked for Monday's flight, but with the "do not open" packet that has obviously been opened. Will she even be allowed to board? If she does, will she have even a 50-50 chance of being allowed into the country? And if not, will she have to return to the consulate in Rio (basically the opposite end of the country) to get the packet resealed, or is this something other US consulates (maybe even the consular agency in Fortaleza?) or ASC can handle?
I doubt any one person can answer all of these questions, but would very much appreciate any partial answers from anyone who can answer part. Thanks.
