Re: There's one bit of good news though
There's a lot more people with dual citizenship in the UK now because of a potential Brexit.
A lot?
Taking the Irish example as the most commonly-sited one:
In August there were 6,710 requests, compared to ~3000 the previous August
In September there were 7,518 applications from the UK compared to 3,431 in 2015.
That's an extra 8K or so. Out of 60m population. Even out of the estimated 2m who are actually eligible it's still hardy "a lot".
