First British passport or child passport from the USA
A first British passport is also the document that settles the question of citizenship on paper. HM Passport Office handles it online from the UK; no consulate is involved.
Who can get a first British passport
The child or adult must already be British. A child born in the U.S. is usually British automatically if a parent was British otherwise than by descent, for example born in the UK. If the parent is British by descent, the child usually needs to register first; our guide to citizenship by descent sorts the cases out.

For an adult who has never had a UK passport, the service warns that a passport interview may be needed, and says it will tell you.
Applying online for a child
You apply through the same service as renewals, choosing that you live outside the UK.
The fee from the U.S. is £75.50, plus the £28.64 courier fee, as the official service showed on 5 October 2026. After you pay, someone confirms the child's identity online; they get an email from HM Passport Office and do not sign a printed photo.
| Document | Why |
|---|---|
| Full birth certificate, with the parents' details | Proves who the parents are |

| Any non-British passport the child holds | The U.S. passport, if there is one |
| Court orders about the child | Where they cover parental responsibility |
Originals or official copies only: gov.uk says photocopies are not accepted, not even certified ones, and documents not in English need a certified translation.
On a paper form from the U.S., the countersignatory may hold a U.S. passport, with a color copy of its photo page.The countersignatory on a paper form
Paper applications need a countersignatory who has known you, or the parent signing, for at least 2 years and who is not a relative or partner.
Outside the UK they can hold a British, Irish, EU, U.S. or Commonwealth passport, according to the countersigning rules; with a non-British, non-Irish passport you add a color photocopy of its photo page, and gov.uk says British or Irish passports make processing faster.
Who signs and what comes back
Someone with parental responsibility signs a child's application. On paper, the documents go in the envelope sent with the form and come back by mail, with secure delivery available for a fee.
If documents are not in English or Welsh, you send certified translations along with the originals, and laminated documents are not accepted (get a passport for your child).
