Each EU country has its own rules about immigration.
A green card is probably equivalent to a permanent residence permit, those vary quite a bit between countries, and skills. Some countries might give a permanent residence in as few as 3 years, I believe quite a few have the 4 years threshold. Depending on what skills you have or how much you invest in the country you are moving to this timeline also shortens.
