The question of what naturalization laws applied at various times has been brought up before, but never satisfactorily answered. I suspect that the regulations were very loosely interpreted and applied in different ways in different locations at different times. It is my impression that an alien had to go to the county court house in their particular jurisdiction and fill out the necessary forms. Perhaps this was done where there was no convenient Federal Court House. However, no one has ever affirmed that going to a court house is correct so if anyone has any specific knowledge or web sites that explain alien registration requirements, please post it so others (and myself) can benefit. The following is the official historical guidelines based on the Department of Immigration and Naturalization: http://uscis.gov/graphics/shared/aboutus/statistics/legishist/index.htm See: <http://uscis.gov/graphics/shared/aboutus/statistics/legishist/463.htm>28.
