To ensure that the Golden Residence Permit programme is a success, the Portuguese government have enacted a highly simplified, 4 stage procedure guaranteeing the issue of the visa within 30 days of submission of your application.
Firstly, you purchase the property in Portugal, either in person or remotely via the internet. You can be gathering the documentation for the application at the same time as you are deciding which property you wish to buy.
Then, we submit the application for you on your behalf — with no personal interview required of you at any time.
Thirdly, the Portuguese Immigration Department consider your application within 30 days and issue the notice of approval and invitation to submit your biometric data.
Finally, you travel to Portugal, complete the fingerprinting and official photograph taking, wait for about 10 days to issue the Visa and then your Golden Residence in Portugal officially commences!
