Hoping somebody here has insight to offer.
I did email the UK Home office but their response was to effectively point me to their website - or an immigration consultant.
Thank you for your further enquiry dated 18th October about citizenship for an adopted child.
Directing you to the guidance material is the only advice we can give you. We cannot tell you which form, if any, you need to use. If you need any further help you should seek independent immigration advice. Immigration advisers can help you with immigration matters, including completion of forms and representing you at a tribunal.
My wife is a natural born British Citizen. We got married in New Zealand, and have lived here since that time with a 6 year period living in the USA
My daughter was born in New Jersey. We adopted her in 2005
When I look on the citizenship website: https://www.gov.uk/apply-citizenship-british-parent/born-between-1983-and-2006
It does not identify specifically what the citizenship status is for those who were adopted, and there appears to be a requirement that my daughter will need to apply for a grant of citizenship, and might receive it "other than by descent" in so doing. I found this from the information here: https://en.wikipedia.org/wiki/British_nationality_law#British_citizenship_by_adoption
The Home office gave a link to search for immigration consultants, but I couldn't find any in New Zealand.
I am hoping someone may have some insight to offer as to how I apply to the Home Office for my daughter to receive citizenship. We want her to have those choices in life that having triple citizenship would offer.
