Most people think of naturalization as a way to stay in the United States. Yet it comes with several advantages. They include the right to vote and better chances of bringing your family to join you. One advantage you may not have realized is it gives you the freedom to leave.
A Green Card restricts your time out of the country
When you are in the country on a Green Card, there is always the chance you could lose it. Being out of the country too long is one reason the immigration authorities could rescind your Green Card or refuse to renew it.
What counts as too long for them may not concur with your definition. You may feel justified in moving back home for a year to care for your sick mother. Or you might feel the opportunity to study in Europe is too good to pass. The immigration authorities may decide your absence means you do not want to live and work permanently in the United States.
Naturalization makes you a U.S. citizen
Once you complete the naturalization process, you will be able to come and go as you please. If you want to spend the next 30 years in another country, you can. If you wish to move to another country and register to pay taxes there, you can. Neither will harm your right to return to the U.S. whenever you want.
Once you become a citizen, you can apply for a U.S. passport
U.S. citizenship makes it easier to travel. A U.S. passport is one of the most valuable in the world. There are few countries you cannot access with one in standard times.
