I enjoy having side projects and currently have 4 active ones that could realistically make at least a some money. But as a foreigner in the US (came as student, now on H1B visa) it's the unfortunate reality that it is illegal for me to pursue money-generating side projects. I am curious to hear if other foreigners have found ways to legally pursue their side projects while living in the US.
