As I write this, I am not sure how much of this proposed hike in United States Citizenship and Immigration Services (USCIS) genealogy type records, the agency that oversees the country’s immigration and naturalization system, will actually happen or is true. This agency maintains a number of applications and documents, including historical records of deceased immigrants.

Many of these items should be free or nominal in cost for Genealogical Research purpose.
