Documents and Process Needed To Apply for Residency after marriage

I am an American male that recently married a Brazilian lady.  I am finding it difficult to understand the process and what is needed to apply for my permanent residency.  My visa will expire in about 30 days so I wanted to get this process started.  Please contact me (anyone) with advice and the website to complete some application form .

30 days visa expiration.... I don´t think you´ll be able to complete the application without being fined for overstay. Besides you need to go back home for the paperworks
needed like FBI clearance, etc.

You can download the forms for application at any Policia Federal website...
