ive done some more research and it seems you have pinpointed the most relevant points.
at the moment my niece lives with my in-laws and i support her financially. i think i am ok fulfilling the criteria. also i am the one adopting and i live in the uk.
after the phils. adoption it seems i have to apply for the settlement visa and then they allow 12months stay to complete the adoption through the uk courts.
a person has to be interviewed and screened by the local council adoption centre etc here in the uk
