Background
Note: This guidance does not include Crown Servants posted overseas whose partner is a non-UK national who does not have a National Insurance number.
If both the Crown Servant and partner are non-European Union (EU) nationals - for example, a Ghurkha married to a Nepalese - the claim should be referred to the Persons from Abroad Team (PFA) for them to consider residency.
