I am my husband's sponsor for his conditional green card. We have a daughter together, but now we want a divorce. I don't want him to lose his green card, but I want out of this marriage and would like to leave. He is able to apply for his 10 year green card in a few months, can I live and work in a separate state until he gets it? If I am his sponsor, after the divorce am I responsible for him for 10 years?
