Long-term residence doesn’t require financial means. So you don’t have to work as long as you meet the other requirements. However, the EU long-term residence permit requires proof of sufficient financial means. In other words, you must be employed or self-employed, or have a bank certificate showing sufficient funds. The EU long-term permit allows you to live and work in any EU country, unlike the long-term residence. If you are considering life in any other EU country, this is your option.
