Opening a company and trading on F1 visa

[immihelp]

As a an F1 visa holder can I:

1.Be the owner of a US corporation?
2.Buy and sell products in the US either personally or through a US corporation?
3.Buy US products and sell them overseas?

Thank you

[immihelp]

1. Yes.
2 & 3. You can't be actively employed for that corporation.

I understand. Thank you.

If I keep in touch with my former clients in the US while on an F1 visa (invite them over for dinner, call and visit them) to resume business dealings after I leave the US, is that OK?

Yes
