Do I apply for both Social Security Disability and Supplemental Security Income?

You can apply for both types of benefits.  Social Security Disability (SSD) is available to those who have worked long enough to quality for SSD benefits (usually 5 of the last 10 years before the date of your disability).  If you have not worked enough to be eligible for SSD benefits, you may still be eligible for Supplemental Security Income (SSI).  Both types of benefits still require proving you are disabled, however, SSI benefits also have a financial component.  Depending on your household income and assets, you may not be eligible for SSI benefits, regardless of disability.  There are no household income or asset limitations on obtaining SSD benefits.
