I'm an American woman my husband is Mexican I want to get him papers how hard is it to get papers

The process will depend upon your husband's immigration history. It is important to know if your husband is in the United States and if so, how did he enter and was he ever in deportation/removal proceedings. If he is not in the country, it is important to know whether he ever was and if so, in what status, how long, and whether he was deported/removed.
