Hello my fiance and i are getting married in march 2017in México. im 23 and he is 18 how long do i have to wait to file in papers for him??

Hello. It can take 9-12 months to process. You can file as soon as you obtain the marriage certificate. There are many aspects and applications with the process.  Here is a general timeline: 1.      I-130 will be process in approximately six (6) months by the USCIS. (If it does not process within the USCIS posted timelines, we can follow up and send inquires after 60 days passed their posted processing date). Within 45-60 days after the approval, the National Visa Center (NVC) will send the fee bill ($445) to proceed with the online application and financial support documentation.  While we wait for this bill, we will prepare the package so it is ready to go after we get the bill. However, we cannot process the online application (DS-260) without the bill.   Once, we submit the DS-260 and all original certificates, financial support, etc., we wait for the U.S. Consulate to schedule the interview. This can range from 1-4 months and depends on the activity of the Consulate and the NVC.
