Illegal? What to do now?

After a month or so of dating I realized that Issac was not in the States legaly. We talked about how we would have issues with getting married if he didn’t do something to become a legal immigrant. Issac began planning a trip to visit a pastor he knew in Houston that could counsel him on the steps that he would need to take. We were both so naive at this point and had no idea what to do. So he had decided that in a months time we was to go to Houston to visit this pastor, and I would wait on him to see what he found out.
