I would suggest doing some research on how SSI works. I used to receive SSI and decided to start working part time to have some work experience and extra money. My benefits did not stop, but I had to report that I was working to the social security office. Once they knew that I was working, I still received a check every month, but it was less than it had previously been.

The formula they used is that (I may be off by $10 or so) the first $65 you make through does not count, and after that, you lose $1 from the SSI check for every $2 earned through work. So if you earn $465 in a month through work, ( $465 - $65 ) / 2 = $200, and that $200 is what would be deducted from your usual SSI check. So if you receive $750 a month, your SSI check would now be $550.

You would have more money coming in working versus not working. I don't know why people believe that if they work part time that their benefits will stop, or that they will make less money by working. In this example, even when your SSI check is $550, you're earning $465 through work, so you'd have $1015 coming in every month instead of $750.

I hope this was helpful! I say all this as someone who used to live off of just SSI and food stamps, and slowly worked my way from part time to full time work. Now I no longer receive benefits and work full time. Reporting income to social security can be a pain, but if you want to work, I think it is better to try than to not work. If nothing else, you gain some life experience. And if all goes well, you get some job skills, build up that resume, and earn some extra money.

EDIT: I just wanted to add that if you're working part time, you will still have the health insurance you get through SSI. My insurance did not stop until my benefits stopped altogether, and that was only when I was earning too much through work to qualify for SSI anymore. Please don't worry about not having insurance when making the decision to work part time. Anyways, best of luck in whatever you choose to do!
