How to get filipino citizenship if i am married to a filipina

He does not need to and it would be unwise to do so.

Why would he not just apply for a Permanent Resident Visa, he's not going to have significantly more rights as a Filipino citizen than he would under a Permanent Resident Visa.

While it is not actually possible to irrevocably renounce British Citizenship it would still introduce a lot of issues for him in that he would surrender his UK passport so would be restricted on where he could and could not travel in future, he would lose access to the NHS, claiming his UK State Pension would probably be a bit harder, he would still qualify for it but I would bet the bureaucracy would be awful.

For me it would not be an advisable course of action.

As Oss mentioned, he can move permanently, to his heart content, but the rest is not the way to go. Too much to loose and nothing to gain.

Way better, can open a bank account will get an ACR card will be able to have services like PLDT and Meralco in his name, will have a special queue at immigration to get through customs, just not allowed to own land but he can own a condo or if you buy a place in your name he will have lifetime rights to live there.

And he retains all of his rights in the UK plus if he had to return to the UK for health reasons he would be able to resume his cover under the NHS, he would have his UK passport which gets him into lots more countries than you are allowed to enter, to me it is a no brainer.

I intend to live out my final years in the Philippines but I would never attempt to cut off my return for me because I am not married to my children's mother I would either have to go the constant renewal route or maybe the SRRV route (special retirement visa) but that requires a substantial deposit of 10,000 USD to be made indefinitely in an approved Philippine bank.

No a house is better, buying a condo is a 50 year lease you never truly own it and it gets harder and harder to sell and less valuable as it gets closer to the end of the lease.

If you already have a house just make sure you don't get fed up with him and throw him out in his old age

You don't need to do that to get Permanent residency the fact he is married to you is enough , read through my link in my first reply.

Regards buying condos most foreign people who buy them buy as an investment to be rented out or at least that is what they should be doing, the rental income over 50 years should be a lot more than the repayments on any loans taken out to buy the property and will definitely be a lot more than the capital invested if the property is bought outright, to me a condo would be just an investment to provide income.

Permanently, he can stay permanently.

13A is the Permanent Resident Visa.

The first year is probationary after that it can be made permanent.

I'm not sure if you can or could in the past apply for this in via the Philippine Embassy in London, I think you might need to go the 9A (normal visitor visa) and convert to a 13A in the country.

These links should be helpful.

Conversion to Non-Quota Immigrant Visa by Marriage (immigration.gov.ph)

Your husband qualifies for a 9A at the current time because he is your husband, just now everyone has to apply for a 9A whereas in the past you could just arrive and receive a visa waiver, you need the 9A just to get to the country the conversion to a 13A is a process that you would do after arriving in the Philippines.

You need to read everything in those links Cheng, the 9A is an ordinary visitor visa it's valid for 59 days I think, but is easily extended, other members have gone down the 13A route and might be able to help you in more detail.

Balikbayan privilege is suspended during the pandemic.
