After we receive your application, we will mail your first claim to you. Claims for subsequent 14-day periods will be mailed to you for as long as you remain unemployed and eligible for benefits. You must complete and return each claim promptly by mail, or file online at www.rrb.gov or you may lose benefits. The time for filing a claim, including time for mailing, is limited to 15 days from the last day of the claim period or 15 days from the date the claim form was mailed to you, whichever is later.
