**Yes—an emergency U.S. passport may be an option.** U.S. embassies and consulates can issue limited-validity emergency passports, generally valid for one year or less. Issuance depends on the circumstances, so you’ll need the consulate to confirm whether your business trip qualifies. [U.S. State Department guidance](https://travel.state.gov/en/passports/renew-replace/limited-validity-passport.html)

**Contact American Citizen Services at the [U.S. Embassy or Consulate in Italy](https://it.usembassy.gov/) now**, giving your departure date, explaining that your passport has expired, and describing the business need. Ask:

- Whether a regular renewal can be completed before departure.
- Whether you qualify for an emergency passport if it cannot.
- What appointment, documents and evidence of travel they require.

An employer’s letter explaining the trip and its dates would be useful to have ready. If you’ve already submitted your renewal, tell them that too. The State Department directs applicants outside the United States to their nearest embassy or consulate for urgent passport assistance.

For this particular trip, check two further points:

- **UK entry:** American visitors generally need an **ETA**, linked to the passport they actually travel with. Confirm acceptance of the particular emergency passport with UKVI and your airline. Meetings and conferences are permitted business visitor activities; other work may require a work visa. [UK ETA rules](https://www.gov.uk/eta), [business visitor rules](https://www.gov.uk/standard-visitor/visit-on-business)
- **Return to Italy:** Carry your valid Italian residence permit alongside your new passport, and confirm that the emergency passport is acceptable for your return and any transit stops.

If the wording on your Italian ID is **“non valida per l’espatrio,”** it means **the card is not valid as a travel document abroad**. It does not itself prohibit you from leaving Italy with appropriate travel documents. [Italian Interior Ministry guidance](https://www.cartaidentita.interno.gov.it/info-utili/viaggiare/)

Your practical next step is an urgent passport enquiry with the U.S. consulate; they can assess both the regular renewal timing and the emergency option.
