The time to obtain citizenship by descent is one of the most determining factors when starting this process. Although many people assume it is a relatively straightforward procedure, the reality is that the duration depends on multiple administrative, documentary, and legal variables.
Citizenship by descent, based on the legal principle of ius sanguinis, allows individuals to acquire the nationality of a country by proving a direct family link to a citizen. However, this right is not granted automatically: it must be validated through a structured process that includes genealogical research, document collection, administrative verification, and final resolution.
Understanding how this process works, what stages it includes, and which factors influence its duration allows for more precise planning and reduces the risk of delays.
What is citizenship by descent and how the process is structured
Citizenship by descent is a legal mechanism that allows individuals to obtain nationality without prior residence in the country, provided a valid line of ancestry can be demonstrated.
The process is built on three fundamental pillars:
- Lineage: existence of a direct relationship with an original citizen
- Documentation: official proof validating each generational link
- Administrative validation: review by the competent authorities
The total processing time is the result of how these three elements interact. The more complex the genealogical chain or the more difficult it is to obtain documentation, the longer the process will take.
Stages of the process and how long each one takes
The citizenship by descent process is not a single action, but a sequence of cumulative stages. Each phase adds time and can become a critical point if not managed properly.
Genealogical research
This phase consists of identifying the ancestor who transmits the right and reconstructing the family tree. It may involve searching civil registries, parish records, or historical archives.
Estimated duration:
- simple cases: 2 to 6 weeks
- complex cases: several months
Common mistake: assuming the lineage is valid without verifying legal interruptions.
Document collection
This includes birth, marriage, and death certificates for each generation. It is one of the longest phases, especially when multiple countries are involved.
Estimated duration:
- organized cases: 2 to 4 months
- complex cases: up to 12 months
Common mistake: submitting incomplete or inconsistent documents.
Legalization and translation
Documents must be apostilled and, in many cases, translated by official translators. This step is mandatory to ensure their international validity.
Impact on timeline:
- can add weeks or months depending on the country
Application submission
The application is submitted at consulates or directly in the country of origin. Appointment availability is one of the main bottlenecks.
Impact on timeline:
- overloaded consulates: months of waiting
- direct application in-country: generally faster
Administrative review and resolution
This is the longest phase. Authorities verify the documentation, validate the lineage, and confirm that all legal requirements are met.
Estimated duration:
- minimum: 12 months
- typical: 18–36 months
Factors that influence processing time
The timeline is not uniform because it depends on specific variables that directly affect the process:
- Country of application: each country has its own administrative capacity
- Consulate: some handle a higher volume of applications
- Complexity of the family tree: more generations require more validations
- Document availability: older records may be difficult to obtain
- Administrative backlog: accumulation of pending cases
- Documentation errors: generate additional delays
The combination of these factors determines the actual processing time.
How long citizenship by descent takes depending on the country
Timelines vary significantly between jurisdictions. Below are indicative ranges based on administrative trends:
Italy
Italy is one of the most in-demand countries. Processing times vary depending on the route:
- in Italy: 1–3 years
- through consulates: 3–5 years or more
Spain
Under the Democratic Memory Law:
- 1–2 years on average
- longer delays in high-demand consulates
Portugal
A more centralized process, with timelines of:
- 2–3 years
Germany and Ireland
Structured processes but still variable:
- 1–3 years
These ranges reflect trends, not guarantees.
Difference between official timeline and real timeline
Authorities usually publish indicative timelines. However, in practice there is a clear difference:
- Official timeline: administrative estimate
- Real timeline: actual time including delays
Factors explaining this difference:
- application backlog
- staff limitations
- additional verifications
For this reason, it is advisable to plan with a wide margin.
Common mistakes that can delay the process
Documentation errors are one of the main causes of delays:
- inconsistencies in names or dates
- incomplete documents
- missing apostille
- incorrect translations
- gaps in the genealogical line
These issues can lead to additional requirements or even suspension of the application.
How to speed up the process strategically
It is not possible to reduce official administrative timelines, but the process can be optimized to avoid delays.
- prepare all documentation before starting
- verify consistency across documents
- choose the most efficient application route
- anticipate legal requirements
- avoid errors from the outset
Strong preparation can significantly reduce overall timelines.
Framework to estimate total processing time
The process can be divided into three blocks:
- document phase: 3–12 months
- administrative phase: 12–36 months
- resolution phase: variable
This model allows for a structured and realistic estimation of timelines.
Real timeline examples
The following scenarios illustrate how duration can vary:
- Simple case: direct line + available documents → 12–18 months
- Medium case: multiple generations → 2–3 years
- Complex case: missing documents → more than 3 years
These examples highlight that case complexity is a determining factor.
Conclusion: how to plan your strategy correctly
The time to obtain citizenship by descent is not a fixed value, but the result of multiple interrelated factors.
The key is not to accelerate the administrative process, but to eliminate friction: properly prepare documentation, understand each stage, and anticipate potential obstacles.
Strategic planning allows you to transform an uncertain process into a controlled one.

Frequently asked questions about citizenship by descent
How long does it take to obtain citizenship by descent?
Generally between 1 and 3 years, although it can exceed this timeframe in complex cases or in overloaded consulates.
Which phase takes the longest?
The administrative review is the longest stage of the process.
Can the process be accelerated?
Not directly, but proper preparation helps reduce delays.
Why is there such a difference between countries?
Due to differences in administrative capacity, application volume, and legal frameworks.
Is it an automatic process?
No, it requires documentary validation and approval by the authorities.
