To qualify for a D7 visa in Portugal, you must demonstrate that you have a regular passive income that is sufficient to support yourself and any dependents. In 2024, the minimum requirement is €760 a month. This income can come from pensions, rental income, dividends, or other non-salaried income sources.
Additionally, you need to show ties to Portugal and the intention to reside there, which could involve renting or buying property in the country.
