Naturalization in Vaud After SEM Authorization – Every Step Explained

If you're going through the ordinary naturalization process in Canton Vaud, here is the specific sequence the canton follows.

The order in Vaud is: Canton (SPOP) → Municipality → Canton (Conseil d'État) → Confederation (SEM) → Oath ceremony.

A distinctive feature of Vaud is that the application is submitted directly to the SPOP (Service de la population), the cantonal authority, rather than to the municipality. The SPOP initiates the process, verifies that formal and material conditions are met, and then transmits the dossier to the municipality for examination.

After the municipality issues its opinion and the Conseil d'État (cantonal executive government) provides a positive opinion for granting cantonal citizenship, the file is forwarded to the SEM for federal authorization.

Once the SEM grants the authorization, you are convoked to a mandatory oath ceremony (prestation de serment) organized by the Canton. This oath before the Conseil d'État or its delegation is the final step — it is at this moment that you simultaneously acquire the bourgeoisie (municipal citizenship), cantonal citizenship, and Swiss nationality. This oath ceremony is a unique and distinctive feature of Vaud's naturalization process.

Another notable aspect: the Vaud cantonal constitution explicitly promotes the naturalization of foreign residents, and the canton charges fees well below administrative costs to encourage naturalization.

Once the SEM grants the federal naturalization authorization, the process in Canton Vaud enters its unique final phase — the oath ceremony. Here is what happens:

Step 1: SEM sends the authorization to the canton The SEM transmits the federal authorization to the SPOP (Service de la population) in Lausanne. At this point, all three levels — municipal, cantonal, and federal — have approved your naturalization.

Step 2: Convocation to the oath ceremony The cantonal department convokes you to the prestation de serment (oath ceremony). This is a mandatory ceremony organized by the Canton of Vaud.

Step 3: The oath ceremony (prestation de serment) You appear before the Conseil d'État (cantonal executive government) or a delegation thereof and make the following solemn promise:

"You promise to be faithful to the Federal Constitution and the Constitution of the Canton of Vaud. You promise to maintain and defend at all times and with all your power the rights, liberties, and independence of your new homeland, to promote and advance its honor and benefit, and also to avoid anything that could cause it loss or damage."

This is a formal and meaningful ceremony that marks the culmination of your naturalization journey.

Step 4: Citizenship is acquired The oath ceremony itself is the legal moment of citizenship acquisition. By taking the oath, you simultaneously acquire the bourgeoisie (municipal citizenship), the droit de cité cantonal (cantonal citizenship), and Swiss nationality. You are now a Swiss citizen.

Critical deadline: You must take the oath within 6 months of receiving the convocation. If you do not appear within this period, your naturalization application is considered withdrawn.

The total naturalization process in Canton Vaud typically takes 24 to 36 months from application to citizenship. Here is a breakdown by phase:

SPOP initial review: a few weeks to months The SPOP receives your application, verifies that the formal and material conditions are met, and includes its opinion in the investigation report before transmitting the dossier to the municipality.

Municipal phase: up to 12 months The municipality has 12 months from receipt of the dossier to process the application and complete the investigation report. This phase includes the knowledge test and integration assessment. The municipality may appoint a naturalization commission responsible for conducting your hearing.

Cantonal decision (Conseil d'État): a few weeks to months After the municipality issues its opinion and the investigation report is complete, the Conseil d'État reviews the file and provides a positive opinion for granting cantonal citizenship.

Federal phase (SEM): up to 8 months The SEM has 8 months to conduct its verifications and pronounce on the federal authorization. This includes security checks and verification of all federal requirements.

Post-SEM — Oath ceremony: within 6 months After the SEM grants the authorization, you are convoked to the oath ceremony. You must take the oath within 6 months of receiving the convocation.

Key deadlines to remember: The municipality has 12 months to process your file, the SEM has 8 months for its review, and you must take the oath within 6 months of convocation. These defined timelines make the Vaud process relatively predictable.

For context, here is the complete naturalization process from start to finish:

1. Application to the SPOP — You download the naturalization form from the canton's website, complete and sign it, and send it to the SPOP (Service de la population) – Secteur des naturalisations with the required documents. Unlike most cantons, the application goes to the cantonal authority, not the municipality.

1. SPOP initial review — The SPOP verifies whether the formal and material naturalization conditions are met and prepares an opinion included in the investigation report.

1. Transmission to the municipality — The SPOP transmits the dossier to your municipality for examination.

1. Municipal investigation — The municipality conducts its own assessment of your integration. This may include a hearing conducted by a naturalization commission appointed by the municipality. The municipality has 12 months to complete this phase.

1. Knowledge test — You take the cantonal knowledge test: a written test with 48 multiple-choice questions covering four themes — history, geography, political institutions, and society — at Swiss, cantonal, and local levels.

1. Municipal opinion — The municipality completes part 2 of the investigation report and sends the complete report with all annexes to the SPOP.

1. Cantonal decision — The Conseil d'État (cantonal executive government) reviews the file. If all conditions are met, it provides a positive opinion for granting cantonal citizenship.

1. Forwarding to SEM — The file is transmitted to the SEM for federal authorization. The SEM has 8 months to complete its review.

1. SEM review and federal authorization — The SEM verifies federal requirements, conducts security checks, and grants the federal naturalization authorization.

1. Oath ceremony — You are convoked to the prestation de serment before the Conseil d'État or its delegation. By taking the oath, you acquire the bourgeoisie, cantonal citizenship, and Swiss nationality simultaneously.

1. Passport and ID — You can now apply for a Swiss passport and identity card.

Here is a breakdown of the fees you can expect throughout the naturalization process in Canton Vaud. Notably, Vaud has some of the lowest naturalization costs in Switzerland, as the cantonal constitution explicitly promotes naturalization and fees are set well below actual administrative costs.

• Federal fee (SEM): CHF 100 per adult, CHF 150 for couples, CHF 50 per minor child
• Cantonal fee (SPOP): CHF 450 for an individual, CHF 550 for a family. Plus CHF 75 per file for identity verification by civil status
• Municipal fee: CHF 100–400 for an individual, CHF 200–500 for a family. Varies by commune (e.g., Lausanne charges CHF 250 per individual)
• Language certification: CHF 200–500 for French B1/A2 exams (if needed)
• Document fees: Varies (apostilles, translations, extracts)

The total cost typically ranges from CHF 700 to 1,200 per person, excluding language exams and document preparation. This makes Vaud one of the most affordable cantons for naturalization in Switzerland — in Lausanne, the total is approximately CHF 800 for an adult.

Good to know: Vaud deliberately keeps naturalization costs low in line with its constitutional commitment to promoting the naturalization of foreign residents.
