My mother in law has indefinite leave to remain in the UK can she ask for help at a British consulate abroad?
British consulates and embassies cannot provide support for non British nationals unless they fit into categories below, even if they legally reside in the UK.
Support for British Nationals Abroad: Summary from WWW.GOV.UK
Who We Can Help
We can provide the support set out in this guide to people outside the UK who are:
British nationals (whether or not they normally live in the UK – see page 6 of main guide)
British nationals with another nationality (known as ‘dual nationals’ – see page 6 of main guide), although this will depend on the circumstances - normally we cannot help dual nationals when they are in the country of their other nationality
Nationals of European Union Member States without a local embassy or consulate
Nationals of other Commonwealth countries where there is not a local embassy, but only in certain circumstances (see page 6 of main guide)
We cannot provide this support to other countries’ nationals, even if they have been living legally in the UK
