Poland does not use the euro as its currency. However, under the terms of their Treaty of Accession with the European Union, all new Member States "shall participate in the Economic and Monetary Union from the date of accession as a Member State with a derogation", which means that Poland is obliged to replace its currency, the złoty, with the euro eventually.
There is no target date for Polish euro adoption, and no fixed date for when the country will join ERM-II (the fifth euro convergence criterion).
BUT if they don't change then its in breach of their Treaty of Accession, meaning all the Poles across the EU will have their immigration status revoked regardless of getting another citizenship or not as it would equate to fraud and Poland would become deeply indebted to the EU for all the loans they have taken.
What are your thoughts.
It was not very long ago that Poland said they will join the EURO in 2015 and it now looks like they keep pushing the date every 5 year to 2020.
So in 2020 it will be 2025... How long will the EU put up with this?
Not to mention Greece is about to default and exit the EU, this will make Brussels tighten up on any loose strings.
I am amazed Poland can get away with it. When it comes to other member states, the lawyers are all rowing in the same bathtub.
