Yes, you will likely need to have your Single Status Document apostilled to have it officially recognized in a foreign country. To be sure, you should confirm with the authority abroad who has requested the Single Status Document. Requirements can vary by situation, by region, and by agency abroad.
For non-apostille countries, you may also need to have the Single Status Document legalized by the embassy or consulate of the destination country.
