My wife has a Indefinite Residency permit. How long can she leave the country at any one time?

Question

So she has her Indefinite residency permit in her passport, but we'd like to go back to China for 6 months to visit her family. (Her parents were refused a visa to visit us and their grandchild they have never seen)

I was just wondering whether my wife will have any problems re-entering the UK after 6 months away. We will be travelling away together with our 2 kids who have British Passports. But I'll be leaving after 4 weeks and she'll follow with the kids around 5 months later.

Thanks

Answer 1

fact. it shouldn't be no more than 2 years CONTINOUSLY. that's the difference between being a british and having ILR. british can go out of the country  indefinitely, and come back anytime. otherwise, your ILR will be revoke.
