Supplemental Security Income is a Social Security program that provides people who didn’t work enough credits a source of income assuming they are disabled. There is temporary disabled which requires recertification to make sure you are still disabled. This is usually done by seeing a doctor they work with. The second is permanently disabled which is when the government has determined that you would not get better enough to work.
One thing to consider is you are allowed to own one house (living in), one automobile, and up to $2,000 in liquid assets. If you have more than $2,000 – then you would endanger losing your benefits. For those in the US, they will know that $2,000 isn’t really enough to live off of rather than having a signifiant amount of money.
