Yes. International students can work at most on-campus jobs for up to 20 hours a week. I thought you meant the federal work-study program in your previous post.
OP should be aware that such on-campus jobs are typically minimum wage or close to it, so they can help provide some cash to offset costs but no where near enough to fund their education. Additionally, proof of existing funds to cover all costs over 4 years will need to be provided to obtain a student visa, and the prospect of an on-campus job won’t count.
