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.
More of your paycheck can be taken to pay child support. Up to 50% of your disposable earnings may be garnished to pay child support if you are currently supporting a spouse or a child who isn't the subject of the order. If you aren't supporting a spouse or child, up to 60% of your earnings may be taken. An additional 5% may be taken if you are more than 12 weeks in arrears.
