Additional evidential requirement for dependants of PBS migrants whose last
grant of leave was not in this capacity.
38. If you are applying as a family member of a PBS migrant and your last grant of leave was
not as their dependant or you are a child born in the UK, you will need to demonstrate your
relationship.
Where you are married or in a civil partnership to a PBS migrant, you must provide your marriage
or civil partnership certificate to support your application
Where you are applying as the partner of a PBS migrant but are not married or in a civil
partnership with them you will need to provide documents to show that you have been living in
a relationship akin to marriage/civil partnership for a period of at least two years - documents
should therefore cover the whole of this period. Documents will only be accepted where they are
from official sources such as utility bills or NHS registration:
Suggested Documents
Partners (including spouses and civil partners)
marriage or civil partnership certificates
bank statements
Council tax/ bills
medical registration
utility bills
