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.
Statute of Limitations. Child support arrears don't go away in Texas unless and until you pay them. There is no statute of limitations for the state to try to collect from you. Even if all your children emancipate and you no longer owe current support, you'll still owe the arrears and you'll still be subject to enforcement measures.
