The main investor can add an unlimited number of eligible applicants to a single residency by investment application.
The main investor must – of course – be over the age of 18 and they can add their spouse, the parents of the main investor, and all of the main investor’s children who are under the age of 18.
In order for additional applicants to qualify as eligible, they must meet all the criteria and not simply the relationship and age components – which can be found on our Portugal Golden Visa page.
