Administrative Appeal: Speed up your file
By law, the Ministry of Justice has one year to resolve your nationality application. If after that year you have not received a response, what is known as "Negative Administrative Silence" occurs.
At this point, many applicants choose to file a Contentious-Administrative Appeal before the National Court (Audiencia Nacional). This step forces the administration to review your file as a priority, drastically reducing waiting times to just a few additional months.
