Once Again, I send this information to you:
Regarding citizenship, Henry is shown as having immigrated in 1906, his status was "Pa." That means "Papers," indicating he had filed his Declaration of Intention to become a citizen. It does NOT mean "pending papers." The term "Pa" was part of the instructions given to persons enumerating the census.
---In the instructions to the enumerators is found, as example for the 1900 Census: http://usa.ipums.org/usa/voliii/inst1900.shtml
-----#151. Column 18. Naturalization.—If the persons is a native of the United States, leave the column blank. If he was born abroad, and has taken no steps toward becoming an American citizen, write "Al" (for alien). If he has declared his intention to become an American citizen and taken out his "first" papers, write "Pa" (for papers). If he has become a full citizen by taking out second or final papers of naturalization, write "Na" (for naturalized).
By continuous use of your term "pending papers" or "pending citizenship papers" it wrongly attaches a different meaning to a CENSUS enumeration and changes it to a Naturalization Process, which is NOT the case. It simply means the person has filed and does not indicate any portion of the process which the word "pending" may indicate. NOTHING IS PENDING.
