The UK government has once again updated passport rules for dual citizens looking to travel to the country.

This time, the government added a rule for dual citizens travelling with expired UK passports.

UK Government Updates Passport Rules Again

As noted by ABC News, the UK government will, beginning Wednesday, require dual citizens travelling to the UK to have either of the following:

A valid UK passport or Irish passport

Any other valid passport with a certificate of entitlement

This applies dual citizens travelling by plan, ferries, and international trains.

However, the UK Home Office has quietly made another change to its website regarding the possibility of travelling with an expired UK passport.

According to the update, it will be the airline's call if it will allow a dual citizen to travel to the UK provided that the person has both of these requirements:

An expired UK passport, issued in 1989 or later

A valid passport for one of the nationalities that can get an electronic travel authorisation (ETA)

What to Keep in Mind Regarding This New Rule

The UK Home Office has emphasized that "It is the carrier's decision whether to allow you to travel" with an expired UK passport.

It should also be noted that the personal details on both passports must match.

The following locations, including associated territories, can apply for an ETA:

Hong Kong Special Administrative Region

Macao Special Administrative Region

Federated States of Micronesia

St Vincent and the Grenadines
