To apply for the social pension for senior citizens in the Philippines, you need to be at least 60 years old and not receiving any other pension. You can start the application process by visiting the nearest Office of Senior Citizens Affairs (OSCA) in your local government. Make sure to bring valid identification and any other required documents. It's also a good idea to check the official website of the Department of Social Welfare and Development (DSWD) for detailed application guidelines and requirements. If in doubt, consulting with a local elder care advisor can be beneficial.
