1. what are different ways in which a person can become a u. s. citizen? 1. why do you think the law requires an immigrant to live in the united states at least five years before he or she can apply to become a naturalized citizen?

1.There are four fundamental ways to obtain U.S. citizenship.
Citizenship through:
1. Naturalization.
2.Acquisition.
3.Derivation.
4.Birth.

2. So they can get used to the country, know its laws, learn about the country itself.
Hope this helps, please mark brainliest!
