What is the difference between Estonia's national long-term resident's permit and EU long-term resident status?

Estonia grants long-term resident status to non-EU/EEA nationals who meet the residence, income, insurance, and language conditions. This is the permanent residence basis for staying in Estonia indefinitely.

Where the status carries EU long-term resident rights, it also gives you a recognised basis to seek residence in other EU countries under EU rules, subject to their own conditions. If your goal includes mobility across Europe later, confirm with the Police and Border Guard Board which status you are receiving.
