Im looking for naturalization records for two immigrants from netherlands.
If FamilySearch has naturalization records for New Jersey you can find them by clicking on "Search" in the upper right hand corner of FamilySearch. In the drop down menu click on "Records". On the page that opens up go to the world map and click on the United States. A box will open up that has the names of all the states; select New Jersey. When you get to the New Jersey page it will have a list of every record collection we have for that state. You may also find the "View Wiki for New Jersey" link which is also on that page, will be helpful.
I am definitely not an expert on naturalization records - - but I would be a bit cautious on restricting your search to just New Jersey.
when one is naturalized in the US - one becomes a US citizen - - not just a New Jersey Citizen.
also just because they are reported to have come to New Jersey - it may be that the actual Port of Entry may have been New York or other ports
