FBI Background Check for Dual Citizenship Applications: The Complete 2026 Guide
Pursuing dual citizenship — whether through ancestry, investment, naturalization, or marriage — almost always requires an apostilled FBI background check as part of your application. Most countries granting citizenship to foreign nationals want proof of a clean criminal record, and for Americans, that means the FBI Identity History Summary authenticated by the US Department of State.
The process used to mean weeks of waiting and significant logistical complexity. With MR Fingerprints, you can get your FBI background check results in 5–7 business days — from wherever you are in the world — without traveling to the United States. Here is a complete guide to the FBI apostille requirements for the most popular dual citizenship programs in 2026.
How the MR Fingerprints Process Works for Dual Citizenship Applicants
Whether you are in London applying for Italian citizenship by descent, in Sydney pursuing Irish citizenship, in Denmark working toward naturalization, or anywhere else in the world, the process is the same:
| ⚡ How the MR Fingerprints Remote Process Works — Results in 5–7 Business Days
Step 1 — Contact MR Fingerprints. Reach out via phone or email to receive detailed instructions specific to your country and situation. Step 2 — Visit your local police station. Most police stations worldwide will take ink fingerprints on a standard fingerprint card as a courtesy for official background check purposes. Bring your instructions from MR Fingerprints. Step 3 — Scan and email your completed ink card. Once your prints are taken, scan the card at high resolution and email it directly to MR Fingerprints. Step 4 — MR Fingerprints submits to the DOJ in Sacramento. We process your submission electronically through the California DOJ system. Step 5 — Results delivered to MR Fingerprints in 5–7 business days. Standard turnaround is 5–7 business days from submission. Need it faster? Ask MR Fingerprints about our 48-hour expedited processing option when you make contact. 📞 Contact us first — we provide personalized instructions for your specific country and document requirements. |
| 💡 Why Speed Matters for Citizenship Applications
Most citizenship programs require the FBI document to be issued within 3–6 months of your consulate appointment. Italian consulate appointments are often booked 12–24 months in advance — timing your FBI check precisely matters. With standard overseas processing taking 6–8 weeks, missing the validity window is a real risk. With MR Fingerprints delivering results in 5–7 business days, you have far more control over timing. Ask about our 48-hour expedited option if your consulate appointment is approaching quickly. |
Why Almost Every Dual Citizenship Program Requires an FBI Background Check
When a foreign government grants citizenship to an American, it is making a permanent decision — admitting someone into its national community with full rights including passport access. Before doing so, virtually every country requires proof that the applicant has no serious criminal history in their country of origin.
For Americans, the FBI Identity History Summary is the gold standard — it is fingerprint-based, federally issued, and covers your complete criminal history across all 50 states. A state-level background check covers only one state and is not accepted by any foreign citizenship authority.
| 💡 The Three-Document Rule for Most Citizenship Applications
Document 1 — FBI Identity History Summary: Fingerprint-based federal background check Document 2 — US Department of State Federal Apostille: Required by all Hague Convention countries Document 3 — Certified Translation: Required by all non-English-speaking countries Missing any one of these three documents will cause rejection of your citizenship application. MR Fingerprints handles all three — contact us to discuss your specific program requirements. |

Italian Citizenship by Descent (Jure Sanguinis) — The Most Popular Program
Italian citizenship by descent is the most popular dual citizenship program among Americans — and the one that generates the most FBI background check requests at MR Fingerprints. Italy has no generational limit on jure sanguinis claims, meaning Americans with Italian great-grandparents or more distant ancestors can potentially claim Italian citizenship and an EU passport.
Key FBI requirements for Italian citizenship by descent:
- FBI Identity History Summary issued within 6 months of your consulate appointment date
- Hard copy with the FBI Section Chief’s original signature and seal — not a printed digital PDF
- Federal apostille from the US Department of State — state apostille not accepted
- Certified Italian translation of the apostilled document
- Submit to the Italian Consulate serving your US jurisdiction — each consulate has slightly different formatting preferences
Italian consulate appointments are notoriously backlogged — often booked 12–24 months in advance. Once you have your appointment date, contact MR Fingerprints immediately to discuss timing. With 5–7 business day turnaround, you have significantly more flexibility over when to order your FBI check relative to your appointment date.
Irish Citizenship by Descent
If one of your grandparents was born in Ireland, you are automatically entitled to Irish citizenship by registering on the Foreign Births Register. The FBI background check requirements:
- FBI Identity History Summary — required as part of character assessment
- Federal apostille from the US Department of State
- No translation required — processed in English
- Submit as part of your Foreign Births Register application to the Irish Department of Foreign Affairs
Current Foreign Births Register processing times are 12–18 months due to high demand. The FBI check should be timed to your expected submission date — contact MR Fingerprints to discuss timing strategy.
Denmark — Citizenship by Naturalization
Denmark grants citizenship by naturalization after 7–9 years of legal residence, with Danish language test and self-sufficiency requirements. FBI check requirements for Danish naturalization:
- FBI Identity History Summary — required for naturalization documentation
- Federal apostille from the US Department of State
- No translation required — Danish immigration authorities accept English-language FBI documents for US applicants
Denmark is one of the countries MR Fingerprints has confirmed is generating active leads. If you are a US citizen living in Denmark pursuing naturalization, contact us for instructions — the process works the same way as for the UK and Australia. Visit your local Danish police station (politiet) for ink fingerprinting, scan and email the card to us, and receive results in 5–7 business days.
Caribbean Citizenship by Investment
All Caribbean citizenship by investment programs — St Kitts and Nevis, Dominica, Grenada, Antigua and Barbuda, St Lucia — require an FBI background check for all adult applicants as part of their due diligence process:
- All Caribbean CBI programs require FBI check for all adult applicants
- Federal apostille required for Hague Convention member Caribbean nations
- Most Caribbean CBI processing happens through authorized agents who coordinate document requirements
- Contact MR Fingerprints to discuss our 48-hour expedited option — CBI timelines are often tight
Frequently Asked Questions
Can I use the same FBI check for multiple citizenship applications?
Potentially yes — if both applications fall within the same validity window. Most countries require the FBI document to be issued within 3–6 months of your application date. If you are pursuing Italian citizenship by descent and Irish citizenship by descent simultaneously, and both consulate submissions happen within the same 3-month window, a single apostilled FBI check may satisfy both. Contact MR Fingerprints to discuss your specific situation and timing.
Does Italy require the hard copy or the digital FBI document?
Italy requires the physical original hard copy of the FBI Identity History Summary with the FBI Section Chief’s original signature and seal — not a printed digital copy. The federal apostille is applied to this original hard copy. When you contact MR Fingerprints, mention that you need a hard copy for Italian consulate submission so we can ensure the correct format is provided.
What if I have a criminal record? Can I still apply for dual citizenship?
Having a criminal record does not automatically disqualify you. Each country evaluates the nature, severity, and recency of the offense. Minor or old offenses often do not affect eligibility. Serious recent offenses are more likely to cause issues. Consult a citizenship attorney for advice specific to your record and your target country before starting the process.
How does the apostille process work and how long does it take?
Once MR Fingerprints delivers your FBI results, we coordinate the federal apostille through the US Department of State Office of Authentications. Standard apostille processing takes 6–8 weeks. Expedited apostille options can reduce this to 1–2 weeks. Note that apostille cannot begin until the FBI document is in hand — the two steps are sequential. Contact us to discuss apostille coordination when you reach out for fingerprinting instructions.
I am living abroad right now. Can I still get my FBI check done?
Yes — from anywhere in the world. Contact MR Fingerprints for instructions. Visit your local police station in whatever country you are living in — most will take ink fingerprints on a standard fingerprint card for official background check purposes. Scan the card and email it to us. We handle submission and deliver results in 5–7 business days. We have processed FBI checks for dual citizenship applicants living in the UK, Australia, Denmark, Trinidad and Tobago, Mexico, and many other countries.
