It shouldn’t be taken away retrospectively unless there’s good reason to think it was a sham marriage. People need peace of mind.
My daughter-in-law is from Eastern Europe and has given up on getting UK citizenship because of the cost and the ludicrous exam she’d have to take.
I still worry that she could be deported even though she’s married to a Brit, is about to give birth to a British baby and is a hard-working tax-paying person.
It seems OK to deprive a dual citizen of citizenship so long as he has one to go to [keep]
some dont allow dual citizens - so ma daydy swore allegiance to the Great White Queen and didnt tell his base country -
and then.... over Rhodesia ( yes that long ago 1966)
renewed his first passport ( Gomboolaland as it then was or some damned country ) - we all thought Kray-zee !
My mother with the 1947 crazy rules for India and Br Raj could never perfect her nationality status ( in-betweeny) - neither one nor the other. She did turn p her nose at Indian nationality
I seriously doubt that if a foreign woman has been here for years & is married to and has a family with a British man that she is in any danger of deportation.
A friend went to Brazil & married & had a child with a Brazilian woman - the fact that he fathered a Brazilian child gave him the right to reside there (not sure about citizenship).
