Dual Citizen Passport Photo Guide: Which Passport to Use When?
Holding two passports gives you flexibility — but it also means managing two sets of photo requirements, renewal schedules, and border control conventions. This guide covers the photo rules for both passports and the practical questions dual nationals face most often.
Country-specific legal note
Some countries (e.g. Germany, Japan) do not officially recognise dual citizenship in all circumstances — consult a qualified legal adviser if uncertain about your situation. The information in this article is general guidance only, not legal advice.
Both Passports Require ICAO-Compliant Photos
As a dual citizen, both passports are independent official travel documents. Each requires a fully compliant biometric photo that meets the ICAO Doc 9303 standard. The core requirements — neutral expression, no glasses, eyes open and looking at the camera, plain background — are the same regardless of which country's passport you are applying for.
What differs between countries is primarily the photo format (dimensions), the required background colour (white vs. light grey), and whether digital or physical submission is accepted. These differences matter when renewing each passport separately.
Which Passport to Use at Which Border
The general principle for dual citizens at border control is straightforward:
Entering a country where you hold citizenship
Use that country's passport. Many countries require their own citizens to enter on their national passport. Using a foreign passport to enter your country of citizenship can cause administrative complications and may be refused.
Entering a country where you are a foreign national
Use the passport that gives you the better entry conditions — for example, a European passport for entering EU countries without a visa, or the passport with a valid visa for your destination.
Exiting a country
Use the same passport you used to enter. Entry and exit records should match. Leaving on a different passport than the one used to enter can cause exit complications.
Booking flights
Use the passport you plan to show at check-in and border control — the name on the ticket should match the passport you will be travelling on.
Handling Different Photo Size Requirements
The most common challenge for dual nationals is that different countries use different photo formats. A German–American dual citizen, for example, needs 35×45mm photos for their German passport and 51×51mm (2×2 inch) photos for their US passport — these are not interchangeable.
| Country | Photo Size | Notes |
|---|---|---|
| 🇩🇪 Germany / 🇨🇭 Switzerland / 🇦🇹 Austria / 🇪🇺 EU | 35×45mm | ICAO standard |
| 🇬🇧 United Kingdom | 35×45mm | Portrait orientation (45mm tall) |
| 🇺🇸 United States | 51×51mm (2×2 inch) | Square format — different from ICAO |
| 🇨🇦 Canada | 50×70mm | Largest common format |
| 🇦🇺 Australia | 35×45mm | ICAO standard, white background only |
Always verify format requirements with each country's official passport authority before applying.
Practical Tips for Keeping Both Passports' Photos Current
Renew both around the same time
If both passports are approaching their expiry dates within a year or two of each other, consider renewing them at the same time. This simplifies photo scheduling and means you only need to organise one photo session for both applications.
Take photos with a consistent appearance
When renewing both passports, take all required photos in the same photo session and with a consistent appearance (same clothing, no changes to facial hair between photos). This avoids inconsistencies that can occasionally raise questions.
Use an online service for correct format conversion
If you need the same base photo in different country formats, a compliant online passport photo service can output the same image in multiple country formats — saving you from having to take separate photos for each country.
Track renewal dates separately
Each passport has its own expiry date. Note them separately and set reminders 6–12 months before each expiry to allow time for renewal without rushing.

Do both of my passports need a new photo when I renew one?
Not automatically. Each passport is renewed independently. When you renew one passport, only that one requires a new photo. However, if the second passport is also approaching expiry or the photos are significantly out of date, it is practical to renew both around the same time.
Which passport should I use when entering my country of birth?
As a general rule, you should enter your country of birth or citizenship using that country's passport. Many countries require their own citizens to enter on their national passport. This avoids complications at border control and ensures you are correctly identified as a citizen rather than a foreign visitor.
Are the photo requirements the same for both passports?
The core biometric requirements are the same (ICAO Doc 9303), but photo dimensions can differ by country. Most European countries use 35×45mm, while the US and Canada use different formats (51×51mm and 50×70mm respectively). You may need separate photos in different sizes if your two passports are from countries with different format requirements.
Does Germany officially recognise dual citizenship?
Germany has historically had strict rules against dual citizenship, but recent reforms have expanded when it is permitted. EU citizens, recognised refugees, and several other groups can hold German and another citizenship simultaneously. If you are unsure whether your specific situation is covered, consult a qualified legal adviser.
Can I use the same photo for both passports?
Only if both countries use exactly the same photo format and both applications are submitted at the same time with the photo taken within the required recency window (typically 6 months). In practice, it is safer and simpler to take matching photos in the correct format for each passport separately.
What should I do at border control as a dual citizen?
Generally, use the passport that matches your citizenship for the country you are entering. When leaving a country, use the passport that you used to enter. Mixing up which passport you use to enter and exit can cause administrative complications, as the entry and exit stamps may not match.
