So clearly I don't know everything but evidence ie. ( the website ) suggest that I know more than you. ;-)
I have three close friends and a number of colleagues, one with children born in Brazil, who have either gone through the process or are going through the process now. One of these now flies executive jets here. I have been interviewed by the Federal Police in several of their cases as a character reference, so I would respectfully suggest that my contact with, and knowledge of, this process extends beyond the confines of a web site. Now if you don't want to know about their experiences, that's fine by me, but why bother asking if you don't want to know?
There is nothing talking about me haveing to wait 7 to 9 years
Explicitly no, but if you know anything at all about Brazil it's not difficult to work out.
From the site you referenced
The required four-year period of residence
So we start with a mandatory four year waiting period, in your case reduced by one year due to having a Brazilian child, so
you must be resident for three years before you can even apply for citizenship.
Now, when does your residence start? It starts on the day your residence visa (RNE) is published by the government. That takes up to 18 months from your date of arrival, assuming that you meet the necessary criteria. Now it can be less, but rarely seems to be below 12-15 months, especially in recent years. If my information isn't good enough for you I would suggest you read some of the comments on this forum from one or two others who are still waiting for their RNEs.
So, in the absolute best case you will have to live and work in Brazil for 3 years and 12 months before you can submit your application. In a more typical scenario you are already closing on 5 years.
Now if a relatively simple residence visa takes up to 18 months how long do you think it takes Brazilian bureaucracy to process a citizenship application? One highly qualified, wealthy, professional friend of mine who works in an industry with few suitably qualified Brazilians put in his application at the end of 2009. He's been told that it will probably be issued early next year. Those who have completed the process suggest that close to three years is the norm.
So we now have a typical case of 18 months waiting for your RNE + 3 years required residence + 3 years for the citizenship process. Now if you are a convicted Italian left-wing terrorist murderer you can cut that right down, but you aren't, are you?
All of that is from the real life experience of friends and colleagues, who have become naturalized Brazilians between 2003 and 2011. Some are pilots, some have Brazilian children, some have invested heavily in Brazil, and all are highly sought after professionals in their field.
Now frankly I don't care if you believe that or not, but whatever you may think, starting here as a foreigner isn't going to be as simple as you think it is, and that is from
personal experience.
