I'm so glad Bajo is here to advise on Immigration issues, we are privileged to have the counsel of an expert for free...Yes, it was a typo mistake.
The ininterrupted residence is abolished since 1956. You need continuous residence.
You do not need the 2 years to apply. 60% of the judges are going to freeze the case until the second year, 40% are going to process your case.
The art. 20 of the NC requires 2 years for obtaing the citizenship.
The uninterrupted 2 years of residency to solicitate means you are enable to request to authorities for 2 years. If you cannot request, then you are not a person and then you are alike a slave. This is why this was a requirement that resurrected with the totalitarian States between the 2 world wars because it was one of the requirements for healing an illegal possesion of slaves during medieval ages.
