If they say they are Brazilian best avoid. Once visited one in Farnborough and said she was Brazilian but is Indian.
Princess Freya was her name, her profile elsewhere said she was Indian.
Also said DFK which she did not do. If they lie about one thing they will lie about other stuff.
Also the Brazilians often look the part but don't do the part. The only part they are interested in is parting you from your you money.
