What exactly can I do, business-wise, on a visa-free entry?

Assuming that my clients are paying my US consultancy (corporation) in USD via check, credit card or bank wire…

Can I conduct short-duration workshops, seminars and training events for corporations in Taiwan? What about 1-on-1 executive coaching?

I’m unsure as to the distinction between “business” and “work” (the former of which is covered by the VWP; the latter of which requires a permit).

Thanks!

Fyi
