Has anyone had experience of this new facility through the gov.br app? I only started using it a few months ago, and it seems really good.
I think it would only be available to permanent visa holders, but might be very useful to those needing to sign documents (even public powers of attorney), without resorting to visiting a cartorio in person, queuing, and pay a fee. It is free, and all done electronically.
If you need to sign anything, you could even do it from abroad, which means that collecting a CRNM for example, may not need an immediate return visit.
