I do not know how database got this information although it would be nicer if it could be true. running a business means earning profit too whether you employ other people or work by yourself. As far as I know, an F-1 can not work outside of the university unless he/she is in practical or some other training. To run a business, you need to get authorization and an F-1 can not possibly run a business and get the earning/benefits from his/her own business. Are there some people who are well-versed in this, by the way?
