I hate to spend the money for a duplicate visa and I feel strange about taking citizenship.
As KFDancer said, you're going to need to do one or the other, because even if your employer doesn't need further proof of right to work, if you are ever asked to prove your right to work for any reason in the future, you currently have no legal proof, because ILR in an expired passport is no longer acceptable proof of right to work.
As per the
Right to Work Checklist on the UKVI website, the only acceptable documents for proving right to work if you hold ILR are:
5. A current Biometric Immigration Document (Biometric Residence Permit) issued by the Home Office to the holder indicating that the person named is allowed to stay indefinitely in the UK, or has no time limit on their stay in the UK.
6. A current passport endorsed to show that the holder is exempt from immigration control, is allowed to stay indefinitely in the UK, has the right of abode in the UK, or has no time limit on their stay in the UK.
You neither have a
current BRP nor do you have a
current passport with ILR sticker... therefore right now, you have no legal proof of right to work.
In regards to citizenship, I get that you might not be comfortable with taking it, but maybe think about it from an immigration POV:
- With ILR, your right to live and work in the UK is dependent on you always continuing to live in the UK. If you were to move back to the US or to another country for more than 2 years, you would lose your ILR forever.
Which means, if you ever wanted to move back to the UK after more than 2 years away, you would have to go through the ENTIRE visa process again and it's much, much harder and more expensive now than when you went through it... for those married to a UK citizen, it means 5 years of visas (spousal visa, FLR(M) visa, ILR), at a cost of around £10,000 over the 5 years (though this is likely to increase in future)
- With citizenship, you will have the right to live and work in the UK for the rest of your life. End of story.
You can live anywhere else in the world for as long as you like, but UK citizenship will give you the right to return to live in the UK at any time for the rest of your life. Not to mention, UK citizenship would also give you the right to vote in the UK.
