My fiance is in prison in South Carolina, hes been there for 2 years or more, his out date is January 21, 2017. We have 2 kids.

Whether he will be able to stay in the United States will depend upon why he is in prison. Some criminal convictions make a person permanently ineligible for immigration benefits while others will require approval of a waiver in order to avoid removal. Without more information it is impossible to determine what, if any, relief from removal is available to your fiancé. What crime was he convicted of committing?
