I am receiving SSD and just recently applied for SSI; should this process take as long as it did for getting approved for SSD? Also, my SSD monthly benefits are very low and earlier this year I had more than the $2000 that a single person is allowed to be approved with; (I have alittle less than the $2000. now tho) do they go by what you have now or do they go back 3 months (or 6 months) or any certain time period? thank you for any help.
