How about the following paragraph from the same link? I think what you meant is reasonable. The reason I want to verify it is because I want to know whether a separate form 1116 and 8832 is necessary in this case. If form 8832 is failed to be provided, any trouble on it?
"The United States is a party to tax treaties that are designed, in part, to prevent double taxation of the same income by the United States and the treaty country. Many treaties do this by allowing you to treat U.S. source income as foreign source income. Certain treaties have special rules you must consider when figuring your foreign tax credit if you are a U.S. citizen residing in the treaty country. These rules generally limit the amount of U.S. source income that is treated as foreign source income. The treaties that provide for this type of restriction include those with Australia, Austria, Bangladesh, Belgium, Bulgaria, Canada, Czech Republic, Denmark, Finland, France, Germany, Iceland, Ireland, Israel, Italy, Japan, Luxembourg, Malta, Mexico, the Netherlands, New Zealand, Portugal, Slovak Republic, Slovenia, South Africa, Spain, Sweden, Switzerland, and the United Kingdom. There is a Worksheet at the end of this publication to help you figure the additional credit that is allowed by reason of these limited re-sourcing rules. But do not use this worksheet to figure the additional credit under the treaties with Australia and New Zealand. In addition, except as provided in regulations, the worksheet does not apply for tax years beginning after August 10, 2010. The amount of income re-sourced in the separate category, as described under “Certain Income Re-Sourced By Treaty,” earlier, must be computed in accordance with the applicable treaty provision."
