If you intend to move to Portugal with your family, the best route would be to invest in real estate and apply for a temporary residence under the ARI/Golden Visa program. The Portuguese Residence Program for Investment Purposes integrates several different types of investments that qualify for an application. Investment amounts may reduce by 20% if the investment is made in a low density territory. Such investments enable you and your family members to apply for a temporary residence in Portugal, which can be renewed every two years. After five years of residence, you and your family will become eligible to apply for either a permanent residence or even the Portuguese citizenship. Regarding the fact that you speak the Portuguese language and live in a country that used to be a Portuguese colony, it would only give you an advantage when applying for the Portuguese citizenship; as for residence purposes, there doesn’t exist any kind of ease by fulfilling that criteria.
