Citizenship issues when giving birth in the Philippines

I know the director of two maternity clinics in Quezon City (not too far from Manila) well. The staff are all women. She'd make sure you have a good experience and take good care of you. If you're interested I can give you the clinic and her name. Wishing you the best. Just remember that care in the Philippines can sometimes be bad, even at good private hospitals. So be careful, but hopefully the delivery goes smoothly. So you're planning to fly there while pregnant and wait for the birth there?

You can leave on either passport. Philippine citizenship passes from parent to child and isn't granted just for being born in the Philippines. So children of foreigners born here don't get a PH passport. I'm a dual citizen and have both passports, but I never use my PH one. It's too much hassle at exit immigration.

If you only get the British passport, you'll also need a visa for your newborn, otherwise when leaving they'd be treated as having stayed illegally since birth. In your case I'd recommend getting both passports. Leave the Philippines on the PH passport and there's no problem, and if you're going to the UK or anywhere else UK passport holders can enter visa-free, arriving on the UK passport is no problem either. The key point is that whatever passport you use to enter a country is the one you have to use to leave it, but it doesn't have to be the same one you use to enter and leave the next country. Getting both passports can take a while, though. The UK passport process is fairly simple and done online, but documents have to be sent to the UK and reviewing and processing them can take months. The PH passport depends on available slots, which can mean shopping around different locations and booking months in advance. So either way, if you want to travel a couple of months after the birth, start the process as soon as possible after the baby is born.

Where are you based right now? I believe the UK has restrictions or conditions a second generation born abroad has to meet to pass citizenship on to a third generation. If the Philippines has no such restrictions (i.e. a citizen's child is always a citizen), that would favor giving birth in the UK. Of course, there may be other reasons that still favor giving birth in the Philippines.

The only obstacle to getting a PH passport for a newborn is the child's name. From what I learned, parents have to give the child the mother's surname as a middle name. So a baby you want to name John Smith, for example, has to be John Tagalog Smith. I fought the law on this for my two kids, and the law won.
