Q: Do I need to provide any supportive document if I am filing N-400 under 5-year eligibility?

A: When filing Form N-400 (Application for Naturalization) under the 5-year eligibility category, you generally don't need to provide extensive supporting documents unless specifically requested by the U.S. Citizenship and Immigration Services (USCIS). The online application system should guide you through the necessary information and documents required.

However, it's essential to have certain documents ready, as the USCIS may request them during the process or at the interview. These documents may include:

1. A copy of your Permanent Resident Card (Green Card)

2. A copy of your marriage certificate and divorce decree (if applicable)

3. Tax returns or transcripts for the past 5 years

4. Proof of continuous residence in the U.S. for the past 5 years (e.g., rental agreements, utility bills, or bank statements)

5. Evidence of good moral character (e.g., character references or affidavits)

Unless the online system specifically asks for these documents or you feel that certain documents strongly support your case, you don't need to upload them in the "Additional evidence" or "Additional information" sections.

It's best to carefully review the instructions provided by the USCIS and follow the online application system's guidance. If you have any doubts or concerns, consider consulting with an experienced immigration attorney who can assess your specific situation and provide personalized advice.
