Sorry to realize this, but just not having a US address or SSN will not help. If you have an overseas issued Visa, Mastercard, AmEx, Discover, or any other US-based credit/debit or ATM card network, the US govt. will cross-check, names, addresses and purchasing histories to identify people who may be avoiding taxes. Also, a task force, including people from the NSA in Maryland, is looking at pulling and pooling data from foreign computer networks as well related to finance, travel, telco, etc.
IIRC, a recent court case was deciding in favor of the IRS and its ability to access records of Visa and Mastercard and ATM networks to identify Americans who were using foreign-based cards.
