Green Card Application (Citizenship/Birthplace)

I am a Filipino but will get my UK Citizenship real soon. Me and my wife are considering the option to move to the US in the future.

My question is, once I get my UK Citizenship and when applying for a Green Card will I be processed as a Filipino (knowing that it will take forever because of the backlog), or as a UK Citizen.

Thanks and God Bless.

as a UK Citizen.

Probably this one if you submit your British passport.

There is still no guarantee you will get a Greencard even with a British Passport and you will still have to follow the same process and procedure as if you were applying with your other nationality.
