Dual Citizenship in Portugal

National Regulations

1. Legal Framework: Portugal allows dual citizenship under Article 3 of the Nationality Law (Law No. 37/81). Citizens can hold multiple nationalities without losing their Portuguese citizenship.
2. Eligibility:
   • Individuals born to a Portuguese parent.
   • Individuals born in Portugal to foreign parents (if at least one parent has resided in Portugal for more than 10 years).
   • Naturalized citizens can retain their original nationality.

General Procedures

1. Application for Dual Citizenship:

   • For Birth: No application needed; citizenship is automatic.
   • For Naturalization: Submit an application to the Portuguese consulate or the local civil registry office in Portugal.
   • Documents Required:
     • Birth certificate.
     • Proof of residence in Portugal (if applicable).
     • Criminal record check.
     • Proof of knowledge of the Portuguese language (A2 level).
     • Application form (available at consulates or online).

2. Processing Time: Typically ranges from 6 months to 1 year, depending on the complexity of the case and the workload of the authorities.

Costs

1. Application Fees:
   • Fees vary by consulate but generally range from €100 to €200.
   • Additional costs may include document translations, apostilles, and legal assistance if required.

Country-Specific Considerations

1. Home Country Laws: Check the dual citizenship laws of your home country, as some countries do not allow dual nationality or may impose restrictions.
2. Tax Implications: Understand the tax obligations in both Portugal and your home country, as dual citizens may be subject to taxation in both jurisdictions.
3. Military Service: Some countries require military service from their citizens, which may affect dual citizens.

Additional Notes

• Renunciation: If you choose to renounce your Portuguese citizenship, you must formally declare this intention to the relevant authorities.
• Rights and Responsibilities: Dual citizens have the same rights and responsibilities as any other Portuguese citizen, including voting and tax obligations.
