Does Argentina Allow Dual Citizenship? What Investors Should Know
Argentina lets you keep your current nationality when you naturalise. What that means for investors, and why your home country's rules decide the rest.
Short answer: yes. Argentina does not ask a naturalised citizen to renounce their existing nationality, and industry sources covering the investment programme confirm no renunciation is required. Whether you can keep your current citizenship depends on your current country’s law, not Argentina’s.
Quick summary
| Question | Answer |

| Does Argentina require renunciation? | No |

What Argentina asks
Argentine law treats naturalised citizens as citizens, and the investment programme announced on 2 October 2026 sets no renunciation condition. Henley & Partners and other firms that cover the programme describe dual citizenship as permitted.
What your home country may ask
Some countries limit or end citizenship when a citizen naturalises elsewhere, or ask for permission first. Others allow dual citizenship freely. Before applying, check:
- Whether your country allows dual nationality at all.
- Whether it needs notice or permission when you naturalise abroad.
- Whether holding a second nationality affects public office, military service or security clearances.
| What to check | Where |
|---|---|
| Your country’s nationality law | Its interior ministry or consulate |
| Effects on tax | A tax adviser in both countries |
| Effects on your children | Both countries’ rules on citizenship by descent |
Travel with two passports
Enter and leave each of your countries of citizenship on that country’s passport where its law requires it. Use the passport that gives you the best access elsewhere, and keep entry and exit on the same passport for each trip.
