There are many exclusive rights that are available only to U.S. citizens. But you can get the same rights after you naturalize:
- You will be able to vote in presidential, senate, and other elections.
- You can be eligible for various government posts. For example, you may be allowed to work as an officer of the Cabinet of the United States.
- You can be an elected official for government offices.
- You will be protected by the United States when you travel outside the U.S. with an American passport. Put simply, you will be able to ask for help in the U.S. Embassy or Consulate in other countries.
- Your child will automatically become U.S. citizens even if they will be born outside the United States (your child will acquire citizenship through parentage).
- Your petitions for your family members are prioritized. For instance, if your family members want to receive their Permanent Resident Card (a green card), your petition for them will be considered earlier than if you were a permanent resident instead of citizen.
- You may require financial aid to study in college, and similar.
Lastly, it is worth mentioning that your status as a naturalized citizen is more stable than if you are a permanent resident (a green card holder). In other words, the U.S. government will not be able to remove you from the country if you are a citizen. But you can quite easily lose your permanent resident status if you do something illegal.
