I was wondering if I could work full time and still draw full ssi check
Hi,
If by SSI you are referring to Supplemental Security Income, then the answer's no. SSI is a needs based benefit, and your SSI payment amount would be reduced by $1 for each $2 that your monthly earnings exceed $65.
On the other hand if you receive Social Security benefits then the answer to your question depends on your age. If you're full retirement age (FRA) or older, you could still draw all of your Social Security benefits regardless of how much you earn. If you'll be under FRA for all of this year then $1 of your benefits would be withheld for each $2 that you earn in excess of $18,240 in 2020. If you reach FRA during 2020 you could earn up to $48,600 in the months before the month you reach FRA without any loss of benefits, but if you earn more than that you'd lose $1 of benefits for each $3 of earnings in excess of $48,600 (https://www.ssa.gov/planners/retire/whileworking.html).
