Information of availability at the national level is listed at
www.archives.gov  (search naturalization).  The records themselves are not available on line.

There are lots of online naturalization records at http://naturalizationrecords.com/  Also it has links to other sites that have naturalization papers

In the middle of the 19th. century, New York was the main entry point for thousands of immigrants ( in 1854 more than 200,000 germans, for instance) so in 1855 the authorities opened up the first "Immigration Centre" at the southern tip of Manhatten, Castle Gardens

In 1892 this was moved to Ellis Island.

Sorry, I have to nit pick a little

Castle Garden existed as a processing station for immigrants between 1855 and 1890. Then there was no processing station for almost 2 years , then Ellis Island, then another period of using the Barge Office, then back to Ellis Island

1624-31 July 1855: no receiving station
1 Aug. 1855-18 Apr. 1890: Castle Garden
19 Apr. 1890-31 Dec. 1891: Barge Office
1 Jan. 1892-14 june 1897: Ellis Island
15 June 1897-16 Dec. 1900: Barge Office
17 Dec. 1900-1924: Ellis Island

As of January 2020:

It appears that Castle Garden is now being called Castle Clinton. See: https://en.wikipedia.org/wiki/Castle_Clinton

Many genealogy websites do not yet give the Castle Clinton name currently used for Castle Garden, so the change may have been relatively recent.

It seems the Castle Garden ship manifests database has been subsumed by the Ellis Island database. See: https://www.libertyellisfoundation.org/expanded-passenger-records-release

This is the link to the Ellis Island Immigration Records, 1820-1957 Search page:  https://www.libertyellisfoundation.org/passenger

I discovered this when a friend to whom I had given links to Castle Garden information could no longer make the links.

Best wishes to all.
