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.
When the amount of alimony or child support is greater than 30% of the FHA borrower's income, the rules can change. The borrower must receive alimony or child support for a full year before applying for the loan. The payer must be obligated to continue paying for three years after the loan has closed.
