I'm currently studying in Birmingham and I entered the country under a Tier 4 student visa on an HKSAR passport.
Last September I decided to renew my BNO which I have held since birth but never used for anything major
I sent HMPO my HKID, BNO, HKSAR, everything they asked for and a few weeks later to my surprise I didn't get my BNO back but I got a full citizenship passport.
Surprised, I called the home office to check that it was ok. The guy on the phone checked through my application and then said that I now have full citizenship and the right of abode in the UK. I've since used my passport to enter through the EU gate, apply for a DBS check and to vote and I've had no issues so I know that my name is on the system as a citizen. However, since my route to citizenship was essentially accidental, I never did the life in the UK test, have a ceremony or get a naturalisation certificate. The only document I have that proves my citizenship is my passport which says citizen on it.
I went to the university and asked them to take me off my tier 4 visa since I was told that I now have citizenship but they wouldn't accept my word, completely understandable, and wants to do an indepth investigation with the home office. Also they found a weird observation on my passport that should only exist on a BNO, aka: this person is allowed to enter the country visa free for 6 months and has right of abode in Hong Kong. In short it's a passport that says GBR citizen but has a BNO observation. They don't contradict each other but they also shouldn't be together.
Obviously, I'm quite worried about having it recalled should it be a clerical error so I didn't allow them to check. Originally I was ignoring the issue by saying that I'll keep my visa up to date as long as I'm in Birmingham and hopefully it'll be ok when I apply for a masters. However, now I'll be studying abroad for a year in the US and the time abroad was not originally part of my degree which means I'll need the university to either accept my citizenship or renew the visa.
The new tier 4 visa laws (Especially the NHS surcharge which I never paid because my original visa application was made before they started) have made it so expensive to apply for an extension that I'm not sure if I can pay for them, nor would I have the time to deal with it right now.
My question then is: Can HMPO recall my citizenship if they gave it to me and I did not make an incorrect application or apply through fraud? Is there any risk in getting the university to check my passport?
I plan on staying in the UK after my degree but as I'm studying an Art subject, it will be difficult to reach the new immigration earnings test so having this passport could be the only way I am able to stay.
