She lives in the UK & is a citizen - she went back because her brother/my uncle (who also lives in the UK) was there before the protests on Holiday & had a pretty serious stroke unfortunately. He needed help getting back to the UK, so his wife and my mum went there to go get him. They've both been in the UK since the revolution.
She hates wearing the hijab & said it was a bit of an interesting time to be back - as many women were openly not wearing a hijab. But also the basiji were out looking for women not wearing hijabs to beat. My Iranian side of the family is pretty anti-religion though, which is understandable because religious zealots ruining a country will do that to people.
