I am 18 years old my fiancé is 18 we plan to get married in may. How old do I have to be to fix him papers ? How much time do we have to be married?

You can get married at age 18. If you are a US citizen, you can sponsor your fiancé immediately after you both get married. The government filing fees are roughly about $1,600 if your to be spouse adjusted his status in the USA. Does he have a criminal record ? Are u employed? You have to show sufficient income to sponsor him, or else you have to find a cosponsor. Roughly $22,000 income on your tax returns is what you need to show or else find a cosponsor. Also needed to know is whether your fiancé has any entries into the USA without inspection or any unlawful visa overstays. The whole process from start to finish takes about a year- California is running longer though. You should work with immigration counsel to help you. Good luck.
