IRS tax form for independent contractors in a foreign country working for a company located in USA?

I am from Brazil and working as an independent contractor for a company in the USA , I need a tax form for them to submit similar to a w-9

1. This would be a Brazilian form. Ask you tax agency what you need.
2. You need to submit a letter asserting that you are a citizen of Brazil and not a US Citizen nor a US resident alien. Since the work is being done in Brazil, it's not US-source work. (If the payer tries to get you to fill out a W-4, W-9 or W-8Ben, the payer has no clue how to do this correctly as none of these apply. There is NO form.)
