`  :I know that not every instance of ``in to`` is wrong (http://public.wsu.edu/~brians/errors/into.html), and I do differentiate between the adverb ``in`` in phrasal verbs (such as ``was sworn in``) and the preposition ``into`` before a prepositional object (as in ``was sworn into office``).   :For example, the article ``Oath of office of the President of the United States`` (version of 01:33, 16 April 2013) says ``William R. King is the only executive official sworn into office on foreign soil.``  (I have not edited that article.) :The expression ``sworn into office`` is used on these external pages. :*President's Swearing-In Ceremony | Inauguration of the President :*Committee History | Inauguration of the President :Those are only two of many pages that I found from a World Wide Web search for sworn into office site:.gov. :There have been many instances where I have seen ``in to`` and I have not changed it to ``into``, but they are not shown in the record of my contributions. :Additional details are in a previous section (#Changing ``in to`` to ``into``). :—  `
