So what does a person that has just been sworn in as a U.S. citizen have to do next on their check list?   Some people might think that they are done and don't have anything else to do with their new rights in the country but we do, check them out here http://www.newcitizen.us/after.html . The page has very interesting information to new citizens, in other tabs it gives it shows us information about voter registration, dual citizenship, passport information, and more. After getting citizenship, I highly recommend getting a passport they are cheap and they will save you the hassle when you do decide to leave the country on a vacation to visit family.
