If you choose to apply with SSA, you must file for the subsidy on an application prescribed by us. A prescribed application may include a printed form, an application our employees complete on computer screens, or an application available online on our Internet Web site (www.socialsecurity.gov). See § 418.3220 for places where an application for the subsidy may be filed and when it is considered filed.
