If you expect to be out of work for a year or longer or you have a terminal condition, you should not delay in filing a claim for Social Security Disability Insurance (SSDI) benefits. You may file your claim for SSDI benefits as soon as you become disabled. You must prove that your disability will last at least 12 months or is expected to result in death. You do NOT need to wait to apply until after you have already been disabled for 12 months. You can apply for Social Security Disability benefits online (www.ssa.gov) or at your local Social Security Office. See also blog posting: How long do I need to wait to apply for SSDI?
