Having birth to child abroad and British citizenship

Dear forum experts,

I applied for my Naturalisation in February 2019 and still awaiting for a decision. Worried too much

My wife moved to UK in February 2019.

I would like to get this information well in advance before planning for a baby. Sorry if it's sounds silly to ask this question at this time.

My wife would like to go back to our home country to look after her elderly parents. More likely she will spend time there for the next 3 years.

1) Let's say if she gives birth to a child abroad, will that child become a British citizen at birth?

2) If we apply for a child British passport from abroad, will Homeoffice expect us to bring that child here any time sooner after getting British citizenship for the child?

3) When my wife decides to move back to UK, will she have any issues getting Spouse visas?

4) If our child gets our home country passport aswell (can keep dual nationality there),will that citizenship have any effect on British citizenship of the child?

Please kindly let me know.

Thanks.

If the child is born after you have become British, then yes, child will be British by descent.

2) If we apply for a child British passport from abroad, will Homeoffice expect us to bring that child here any time sooner after getting British citizenship for the child?

No.

3) When my wife decides to move back to UK, will she have any issues getting Spouse visas?

No, you will have to meet the same requirements again from scratch, or whatever they might be at that time.

4) If our child gets our home country passport aswell (can keep dual nationality there),will that citizenship have any effect on British citizenship of the child?

The UK allows dual nationality!!!

Thanks ever so much CR001. I hope you are keeping well. Take care.
