Q: I retired under a medical retirement. I am married and got my Federal Employees Retirement System and Social Security Disability Insurance. If this combined income is not enough to live on, is it possible for me to apply for Supplemental Security Income for my spouse and myself? A: You can always apply for Supplemental Security Income. Whether your request would be approved depends on a number of factors. I suggest that you go to the Social Security Administration website at http://www.socialsecurity.gov/pub/11000.html and review the criteria. Information about how to apply for benefits is also provided on that site.
