Is it legal to trade stocks in USA's stock exchanges as an Indian citizen?

@nithin I had a doubt about this. I came across a post on a different thread that mentioned that Interactive Brokers allowed buying options (and deploying certain other options strategies) in the cash account. The poster was also skeptical if this was in accordance with LRS. After that, they asked Interactive Brokers multiple times, who confirmed that it was in compliance with LRS. Given that Interactive Brokers has done their due diligence on this matter, would you suggest it is all right to go ahead with it?
