4. Avoid highlighting, crossing out, or typing or printing outside the area provided for a response. If you must makesubstantial corrections to your Form N-400, USCIS recommends that you start a new Form N-400 rather than using
correction tape or fluid to correct the information. USCIS scanners may see through the white correction tape or fluid.
This may lead to incorrect information being captured in USCIS systems, which may cause processing delays or arejection (non-acceptance) of your Form N-400.
5. Provide your A-Number on the top right corner of each page (if any). Your A-Number is located on your Permanent
Resident Card (formerly known as the Alien Registration Card). The A-Number on your card consists of a seven tonine digit number, depending on when your record was created. If the A-Number on your card has fewer than nine
digits, place enough zeros before the first number to make a total of nine digits on Form N-400. For example, type or
print number A1234567 as A001234567 or type or print number A12345678 as A012345678.

Early Filing. An applicant filing under the general naturalization provision (section 316(a) of the INA) may file his or
her application up to 90 days before he or she would first meet the required 5-year period of continuous residence as alawful permanent resident (LPR). An applicant filing as the spouse of a U.S. citizen under section 319(a) of the INA may
file up to 90 days before meeting the required 3-year period of continuous residence as an LPR. Although an applicant
may file early according to the 90-day early filing provision, the applicant is not eligible for naturalization until he or she
has reached the required 3- or 5-year period of continuous residence as an LPR. Applicants filing up to 90 days before
meeting the continuous residence requirement must still meet all other requirements for naturalization at the time of filing
Form N-400. For example, an applicant filing under section 319(a) of the INA must meet all other requirements as the
