What kinds of tax forms I will receive?

Hi, every one.

I’m a F-1 visa student. And I’m only here for two years, which means, I’m a NRA (non-residence alien). What kinds of tax forms I will receive if use Alpaca to trade?

My concern is: I noticed that the contrast mentioned “W9 certification”. I’m not sure if it means I will receive W9 form. Because a NRA seems not supposed to receive W9.

If there are some f1 NRA student have used alpaca, could you share your experience? Thank you all!
