To apply for the social pension for senior citizens in the Philippines, you'll need to visit your local Office of the Senior Citizen Affairs (OSCA). Bring required documents, such as your valid ID and proof of age. The OSCA will assist you in completing the application. Approval and payment will be processed by the Department of Social Welfare and Development (DSWD), so it’s best to check with them for any specific requirements or updates in the process. For the most accurate information, visit the DSWD's official website or contact them directly.
