What is the difference between permanent residence status and passport of European immigrants?

Permanent residence, as its name implies, refers to the permanent residence granted by the state to eligible immigrants and their family members in the country. If you apply for permanent residence, you can get the long-term residence qualification in the country, as well as free public education benefits and corresponding public medical services.

Compared with permanent residence status, passport holders can also enjoy visa-free/landing visa benefits of their host countries' passports. According to the Heinz Passport Index, among the top 10 passports with the largest number of visa-free/landing visa in the world, 23 passports are from EU member states.

At present, the immigration status of Portugal, Ireland and other countries is one of the popular ways to obtain EU passports.
