hi everyone

We are planning to apply for spouse visa soon. I would like to ask if it happen that my visa is granted and I will travel more than after 3 months allowance due to giving birth,do I need to get British passport for the baby after giving birth here in Philippines before traveling in the UK ? how long the passport for the baby to process? (my british husband is the father )
Am I not allow to apply for Indefinite Leave to Remain in UK once the remaining validity of my visa cant reach 2 years? do I need to go back in the Philippines before the validity of my visa ends and apply for FLR again ?

hope you can give me advice.

thank you
