What's the difference between Portuguese residency, permanent residency and passport?

The right of abode includes permanent right of abode and temporary right of abode. There is a time limit for temporary residence, such as two years. Whether you can get temporary residency again after the expiration of two years is decided by the Portuguese Immigration Department.

Permanent residence refers to the right of permanent residence. The right of permanent residence is permanent and indefinite. As long as you have not violated the relevant provisions of Portuguese immigration law, this right will not be deprived. Although the permanent residence card is valid for 5 years, it will not be renewed until it expires, and it is not necessary to reapply for permanent residence in the next 5 years.

There is no difference between a temporary residence and a permanent residence except for the time limit.

Holding a Portuguese passport means becoming a Portuguese citizen. The prerequisite for naturalization is to obtain permanent residency first, and then meet other naturalization conditions. After naturalization, you can get the right to vote and stand for election in Portugal, otherwise it is no different from permanent residence.

Of course, it is more convenient to travel internationally with a Portuguese passport, and there are many visa-free countries. Portuguese permanent or temporary residents all hold China passports, and there are few visa-free countries.
