Yes, you can claim your Philippine SSS pension even if you’re already a naturalized citizen of another country.
I’m not working with SSS, but these are my basis:
1. Basically, you are still a Filipino citizen.
Republic Act No. 9225, known as the Citizenship Retention and Reacquisition Act of 2003, declares that natural-born citizens of the Philippines who become citizens of another country shall be deemed not to have lost their Philippine citizenship.
2. There are already many Filipinos who have been naturalized citizens of other countries that have been receiving their Philippine SSS pensions monthly.
Filipino pensioners abroad have been filing their ACOP or Annual Confirmation of Pensioner’s Form every year on their birthday month. Many have been using Visa debit cards to receive their SSS pension monthly. Recently, it’s Chinatrust (now CTBC Philippines) that has been issuing Visa debit cash cards for SSS pension withdrawals abroad.
3. The case of Philippine SSS pensioner in the UK, Mrs. Epigenia Belarmino, shows that Filipinos naturalized as citizens of other countries can claim their Philippine SSS pensions. She was featured on the UK-based Pinoy news site AdoboRice.
As published by AdoboRice, Mrs. Belarmino, a British citizen living in the UK, received her lumpsum benefit of 332,817.12 pesos in 2012, representing the total of her monthly pensions for 5 years, which accumulated because she filed at age 70. She also started receiving her monthly pension of 3,513.84, which will be for life. She was thankful to the SSS office at the Philippine Embassy in London for helping her process her pension.
While working in the Philippines from August 1957 to July 1977, Mrs. Belarmino paid contributions to the SSS, accumulating a total of 20 credited years and total contributions of 3,176.06 pesos.
4. Section 15 of the 1997 Philippine SSS Law states that the SSS may pay benefits without regard to nationality or country of residence. It also implies that a national of a foreign country can receive SSS benefits as long as his or her country is recognized by the Philippines and is also extending benefits to Filipino beneficiaries in the Philippines.
