SSI: Money In A Hurry
You can walk out of the Social Security office with a check the same day you apply for Supplemental Security Income (SSI) if your medical condition qualifies you for the Presumptive Disability Program. Under the program, you can receive up to six months of SSI payments while you complete the paperwork and your claim is reviewed.
Once you qualify for SSI, you can also get an advance of all or a part of the next month's SSI payment for an immediate, urgent need such as an emergency.
If you receive presumptive SSI benefits, they only last for six months. Therefore, it's in your interest to get your paperwork in as soon as possible, so your situation can be reviewed and approved within the six month period. If you are not approved within six months, payments will stop.
