@veronicabiondi you can immigrate to the US with a husband in prison , it has been done by a few people on this site and others who are not. There was a women from France who immigranted to the US with her husband on death row so it's not impossible. As for the interview ,USCIS policy Manuel chapter 5 - interview guidelines clearly stated the interview can be waived for incarcerated petitioners. If you look up @Mattelo on this site you will see she successfully received her green card with a husband who has a life sentence. If you can prove your marriage is valid , you obviously can because you have the evidence to show , you can prove you will not need government assistance and or have joint sponsor who meets the requirements there is NO reason for your green card to be denied. @Jill Mackie mentioned on this post , uploaded 400+ pages of evidence of an 7 year relationship. That's longer most people who have a "normal marriage" stay married for . You could easily complete the application yourself without wasting money on an attorney , most of them are clueless when it comes to cases that are out of the norm. It can be done , it has been done , so you should be just fine. Good luck and don't listen to those who judge , it's nobody's business but yours.
