What if he was issued an IRL confirmation letter instead, sent that in when getting naturalised, and the home office subsequently kept/destroyed the letter? That is similar to this BRP situation.secret.simon wrote: ↑Tue Apr 09, 2019 2:17 amI doubt there would be many people in this position.
The requirement to destroy BRPs (which only started getting issued in the past ten years) only came in in the past three-four years.
The policy only adversely affects children born after one parent acquired an ILR BRP, but whose parent subsequently naturalized in the past three-four years. That is a relatively narrow field. While certainly in the hundreds, and possibly the low thousands, I'm fairly certain that it would not impact hundreds of thousands of applicants.
If your father acquired ILR in the 1980s, that would have been stamped into his non-British passport. Passports are the property of the government that issue them and it is highly unlikely that the British government would have damaged or destroyed any part of a non-British passport. Therefore, the proof of your British citizenship by birth in the UK to a settled parent would your father's non-British passport with the ILR stamp or vignette dated before your birth and have nothing to do with the BRP destruction point made by Vinny and Obie.
I agree they wouldn't keep/destroy foreign passports.
