Form W9 question

[spm5166]

I am on a H1 visa with Company A. I helped Company B with a very small project and they would want to compensate me for my efforts. The compensation is $125 and they would want me to fill out a Form W9 to proceed.

Is it legal to accept payment? Can you all think of any other way?

Thanks in advance.
