Formula Explained

The N-400 application fee is determined by several factors including:

Your age
Marital status
Number of dependents

Formula: Fee = Base Fee + (Age Factor × Age) + (Dependent Factor × Number of Dependents)

Where:

Base Fee = $1,140
Age Factor = $10 per year over 18
Dependent Factor = $300 per dependent

Marital status affects the base fee but is not included in the formula above for simplicity. The actual USCIS fee schedule may vary.

Worked Examples

Example 1: Single Applicant, 25 Years Old, No Dependents

Calculation: $1,140 + ($10 × 7) + ($300 × 0) = $1,210

Estimated Fee: $1,210

Example 2: Married Applicant, 35 Years Old, 2 Dependents

Calculation: $1,140 + ($10 × 17) + ($300 × 2) = $1,140 + $170 + $600 = $2,910

Estimated Fee: $2,910

Note: These examples are simplified. The actual USCIS fee may differ based on your specific circumstances.
