how long before a decision from SSI
If you are approved for Social Security Disability (SSDI) benefits, your benefits will begin to accrue twelve months before your 2012 application. If you were approved for Supplemental Security Income (SSI), your SSI benefits will begin to accrue the month after the month of your application.any decision letters take sixty days or more. Then, if you applied for Social Security only and not Supplemental Security Income (SSI), and you are currently owed money, it can take from two weeks to two months or more to receive benefits.
