Update:
Seems to be easier now to apply for citizenship because as soon as the decree requires legal residencia (green card) and the legal competency of the judge cannot be delegated in the Executive Power, I m asking judges to order immigration to provide a DNI to full fit the new requirements, and it must be for free according to the free of fees principle of the citizenship procedure.
There was a new precedent last week in this way.
The second consequence is that the files has to be update to the new decree, so, it takes some time.
However, even it is still possible to get citizenship without previos legal residencia, now amateurs are out of business.
