This question is going to be quite specific, but to cut a long story short, i'm a UK-EEA national residing in the EEA state of which I hold citizenship - apparently rendering me unable to use the EEA FP entry route to bring over my non-EEA spouse (as I do not invoke free movement treaty rights).
If we insist on using this immigration pathway, the two options I have are a) renunciation of either citizenship or b) not declaring a citizenship on the EEA FP Home Office application. For curiosity's sake, I were to take option B, could anyone tell me which of the three would most likely lead to a successful application; declaring UK/undeclaring EEA, declaring EEA/undeclaring UK, declaring UK+EEA?
1- I renewed my UK passport in July 2019 and, because I couldn't afford to be passportless for 1+ month, did not declare my extra citizenship on the online form. They sent me my new one without a problem, and i've never used it nor used the older one for several years.
2- I have used my EEA passport at various UK airport border e-gates, most recently July 2020.
So is there a database the home office can use to cross-reference my UK passport name against a list of all inbound passengers? Would they check if an EEA-only FP applicant also has a UK nationality?
I could really use a home office caseworker right now :)
