@pete920 , where you can assert treaty conditions/article benefits depend on (a) your immigration/tax status, (b) your tax home (c) income type and source and (d) what you are actually talking about. Tax treaty itself covers only some types of income.
Please tell more ( along the line outlined above ). I will circle back once I hear from you.
If you do not wish to expose all the info on this public board, you can always choose to PM/DM me -- just no PII ( Personally Identifiable Information)-- use the little envelope thingy above right on the ribbon.
