To become a legal US citizen, the United States has to define what are the rules necessary for anyone to apply for US citizenship.

Explanation:

Residing in another nation is the desire of many people. The search for a job and study opportunity in another country is huge, with the United States being the most sought by Brazilians who want to live abroad.

The US government must disclose the rules to become a US citizen and disclose any changes to the guidelines if they happen. The individual interested in obtaining US citizenship, in turn, must be aware of all rules (including the necessary documentation) in order to receive citizenship.
