The completed and signed form must be received by an RRB office within 10 days of the first day for which you want to claim benefits. You may lose benefits if your application is filed late. If the form is late, enclose an explanation.
Once your application has been processed, a claim form will be mailed to you for completion. You must complete and return the claim to the RRB office whose address appears on the claim. A notice of the claim will be sent to your employer. A claim for the next 14-day period will be mailed to you on or about the last day of the period covered by the claim.
