If you have provided your agency with documentation of your disability and your agency has attempted to accommodate you through all available methods without success, then you can apply for disability retirement under the Federal Employees Retirement System.   To apply, you must fill out the Application for Immediate Retirement and Documentation In Support of Disability Retirement. Your agency will help you fill these forms out, and they will forward the forms to the Office of Personnel Management. Note that the Office of Personnel Management must receive your disability retirement application within one year of your separation from your agency. If you have been separated from your agency for more than 31 days, submit your application directly to the Office of Personnel Management instead of going through your former employer agency. For more information on disability retirement eligibility and the application process, click here.
