If my wages earned abroad are exempt from taxation in the US due to an intl treaty for the avoidance of double taxation, can I file 1116 or declare the foreign income?

This is a case of  "you cannot have your cake and eat it too" and if you go the exclusion route by making the election then you cannot just change back to the tax credit at will ... if you revoke the exclusion then you cannot make it again for a 5 year period so think on it carefully.

Thank you! My intention is not changing the way of filling, which is form 1116 so far. I just want to be sure that I am not falsely taking the tax credit. Am I obliged to take the exemption from US taxation of my foreign wages that the international treaty mentions? I prefer not.
