FYI, each US State is different in how divorce decrees are handled. "Decree Absolute" is a British term and only used in the US States that call themselves "Commonwealth", MA, KY, PA, and VA. A US State Dept. link has already been given, which when the country is selected, tells the reader the exact acceptable document or documents, as well as how they can be obtained.
That's the source. Randomly searching for something available in MA, would be highly counterproductive.
