Are More People Moving Back to Brasil?

I've been a bit out of the loop in terms of the Brazilian community in SF as of the last several months but there was an article in one of the major newspapers on the East Coast (maybe NYT) last year about Brazilians moving back home due to the economy here. Interestingly, there's a bit of a movement for American expats in Brazil moving back home after up to 2 years in Brazil. It seems that for those who are exploring life and seeing where it takes them, there's a limited number of years they normally stay in another country, no matter if an American in Brazil or a Brazilian in the US. Of course, there are those who come/go with the intention to stay so that's different. Different strokes for different folks.
Remember, though, that Brazilians going back now who have a job waiting for them in Brazil will be better off that those who have saved up money here in order to exchange it into Reals back home due to the weak dollar, they won't get as much as they would have. As of recent and according to the news, you may also see an influx of Brazilians in the US, but as tourists, since their economy is booming.

I imagine people come & go for different reasons as the economy is certainly a factor. Add to the fact that with an improving economy in Brasil, including the upcoming World Cup and Olympics must be creating even more opportunities that it would be advantageous to move back home to Brasil. Making money, being home & with their family is a win-win for them. When & why people return to Brasil is certainly their business but my main point is that I am saddedned by their departures and the effect it has on the Brazilian community here, and to people like me who loves the community and culture.
Apparently from the articles you cited and observations it is apparent that this trend is not localized to my area here in Boston but throughout the USA. Sure many or most don't intend to stay forever but what is striking is the lack of influx of Brazilians to the USA. Based on what I understand, you are correct that their are more Brazilian tourists coming these days visiting the USA and not as many "expats" looking to come and help support their family they left behind. The falling Reais only discourages people to come here and work even more as it effects the amount they are able to send back home to their families.
As for the American expats down in Brasil, I can't say since I am not one nor(unfortunately) ever been to Brasil but I imagine the younger the expat the more likely their stay to be shorter or at least temporary. Older people, unless they go to escape the winter season such as our "snowbirds" to Florida are less inclined to move and more able to invest in a property, probably to retire. A lot will depend on what my future wife feels but I hope to one day have the opportunity to move down to Brasil, most likely to her native Pernambuco. How long would I stay? I'll let you guys know once I get down to Recife! kkk
Again it was just a casual observation as it seemed a number of people, far more than ever were moving back home and I found it odd, interesting and as mentioned, sad. Muito obrigado.  Jimmy
