there is a social security board here and also at that other site i cant mention on here.

what you would file for would depend on how many work credits you have. at 30 you would need to have half of the work credits that you could have possibly had by working from 21 until the time you are disabled. At 31 you would need 20 work credits or quarters. there are 4 work credits in a year you can earn but it doesnt mean you have to work the whole year it would depend on how much you made that year. right now its 1000 dollars a credit so if you earned 4,000 even if you earned it in one month you would get 4 credits. if you dont have enough work credits for ssdi then you could apply for ssi which is also disability but is income based.

it could take 3 months to over 3 years to know if you are successful in your application depending on what level you are approved.
