Yes you can. I'm not sure what the amount limit is though, since I have only ever worked part-time. Where I live, you get $100 extra a month if you have a job, plus the first $200 you make is not penalized. So technically the first $300 you earn is not affected. Afterwards, for every dollar you make, $0.50 is taken off your next disability check. I imagine this is different in the U.S though. Good luck!
