Dear friend,
I am from pakistan I earn some revenue from any site but now the company requirement must fill the form W-8BEN...
What I do ? I am so anxious how will I fill this form ?
Please guide to me I am totally blank about this term.. can I hold my earning ? How ?

If you live and work in Pakistan that is you are not present in the U.S. to work for the site, then you will file Form W-8BEN.

This is to state that you are a foreign national and your income is not subject to the U.S. taxes.
