After filing Form N-400, Application for Naturalization, the entire naturalization process can take anywhere from 5-8 months. This is an approximation. It may be shorter for some and longer for others.
Best Answer Thanks! I assume from your question that you have a court order for child support that ordered your ex to pay the $820 per month. Assuming this to be the case, and assuming that the court did not allow your ex to reduce his payment, you can go back 10 years to collect arrearages.
If you overpay your income taxes and have an amount eligible for a refund, the state agency that governs your child support order has first claim to that refund if your support payments are unpaid. The state can continue to garnish tax refunds each year until all child support payment obligations are satisfied.
