The application for naturalization is the first and likely most important step in the naturalization process. As an individual must follow an established process to become a naturalized citizen of that country, the first and most important step is to file the application in its entirety. If an individual hopes to have a smooth process that results in their naturalization, then they must be honest and forthcoming about all of the information provided on this application. The application for naturalization is what the government will refer back to when they hope to gain information on an individual throughout the naturalization process so it's an essential part of the process.
