Consequences of dual citizenship
There are several consequences of dual nationality that you should note:
- The nationality laws of the country of which you’re already a citizen may not allow dual nationality.
- Under the nationality laws of some countries, a married person automatically takes on their partner's nationality. Children may also automatically take on a parent's nationality even if they were born abroad.
Under international law, a country cannot give diplomatic assistance if you are resident in a country of which you are a national. For example, if you hold both UK and Chinese nationality, the UK would be unable to give you diplomatic assistance when you are visiting or resident in China.
Your existing nationality, and that of your partner or children, could be compromised if you take on Australian nationality. You should always seek professional advice when obtaining dual nationality, especially before you travel internationally.
UK and dual citizenship
The United Kingdom allows dual nationality. However, if you hold one of the other four forms of British nationality, different rules apply and you must seek further advice.
Please note: Obtaining a second nationality can mean the automatic loss of one of these four British nationalities. Always consult an expert when applying for a new nationality.
