Hi !

I have a quetion: should a a non resident allien report US stock capital gain ?

He is a Chinese citizen and resident and has rentals in US and recieving passive income. So he files 1040NR. BUt this year got Schwab 1099B for stock gain he sold. 

Does he need to report this capital gain on the 1040NR? 

Anyone familiar with the treaty ? 

Thank you very mich!
