To apply for senior citizen benefits in the Philippines, you can visit the official website of the Department of Social Welfare and Development (DSWD) or your local government unit's (LGU) site. Typically, you’ll need to provide some documentation, such as proof of age and residency. Each LGU may have specific online processes, so it's advisable to check their instructions closely. If you're unsure, contacting local officials or visiting their offices could provide additional guidance. Always ensure you’re following the most current regulations and procedures.
