As the referenced article above, provided by VidaNaPraia, indicates, the fingerprinting that Brazil implemented back in 2004 was a reciprocity action due to the US implementing fingerprinting of all aliens, not just Brazilians. Prior to 2008, I made trips to Brazil about 2 or 3 times a year. From 2008 until 2016 I was traveling back and forth between Brazil and the US monthly. Brazil's finger printing lasted about all of 6 months, if that long, as I was only finger printed once. During my monthly trip period, not at all. My most recent entry was in July this year and there was no finger printing. I travel again next week and if something has changed, I will report it here.
