I want to work with Commission Junction (www.cj.com) and they ask me to complete a W9. The problem is that they work only with US citizens and I'm not, but I worked before in US and I have a SSN, but now I am outside of US and I don't have a visa. What if I complete the W9 form with my SSN and a US address, does the IRS receive any informations about my income from them or just if I declare that income? I mention that the income I will get in a bank account from another country, so I will not use any bank account in US. Are there any risks?
