Hi Boo the answer to your question is this, SSI IS BASED ON YOUR INCOME AND THE SSDI IS BASED ON YOUR WORK HISTORY.I just posted some info under another thread here it is. In your case since you don't have the work history yours would not be a 6 month trial as long as they find you medically disable, that decision was made in 5 months for me.
This is the way it work in Tennessee, I applied for both in August 2010 on January 3 2011 SSI called to say they found me medically disable and that I was approved for SSI, after asking me several questions, about income, my household and did I get any help from others, she basically said that I did not meet income status. Because SSI IS BASICALLY A WELFARE TYPE PROGRAM AND THIS IS WHAT SHE SAID. SSI is only a mean of income until the final decision is made with the SSDI, she said that the local office make the decision on SSI and another location makes the decision on SSDI.If SSDI IS APPROVED THE SSI PAYMENTS WOULD BE DEDUCTED FROM MY SSDI, BUT IF SSDI WAS NOT APPROVED I WOULD NOT HAVE TO PAY THIS BACK, IT IS ALSO JUST A 6 MONTH TRIAL OF INCOME OF SSI. Since I had a income of more than the 674.00 that Tennessee gives under the SSI, I DID NOT QUALIFY FOR THE SSI.
EXAMPLE IF MY MONTHLY INCOME WAS 300.00 THEY WOULD GIVE ME 374.00 IN SSI. I AM GLAD I DID NOT QUALIFY!!!!
