How long is the investor visa valid for?
Your residency status is permanent in the sense that you can live and work in Brazil without a time limit. However, your permanent residency is linked to your status as an investor in the country. Therefore, in order to renew your documents, the authorities will periodically check if you have kept your investment in the country; if it has been repatriated, you visa may be annulled. The first time will be after three years. The renewed visa will be valid for 9 years before renewal, but after the visa holder becomes 60 years old, it will be no longer necessary to renew the document. You can also apply for citizenship and will no longer need to renew your visa after that.
