Is Stock Trading legal for a student on F-1 Visa in USA? [duplicate]
As an F1 student, I have been investing (and occasionally buying and selling within few weeks) for several years, and I have never had problems (of course I report to IRS gains/losses every year at tax time). On the other hand, the officer in charge of foreign students at my school advised me to not run ads on a website and make a profit. So, it seems to me that investing is perfectly legit for a F1 student, as it's not considered a business activity. That's obviously my personal understanding, you may want to speak with an immigration attorney to be on the safe side.
