I had read an official document in the past that stated that EU citizens exercising their right to free movement within the EU must be a citizen of (or have lived in) an EU country for at least 5 years in order to exercise their right to move to Ireland.
However I cannot find the document now.
Is this fact true?
Example: If you just naturalized as a French citizen, you wait at least 5 years to exercise free movement rights to move to Ireland.
