Encouragement for Converts

Question: There are many people who converted and have lived many years as Jews only to find out recently that their conversions are not recognized by rabbinical authorities in Israel and the US. What would you say to the people whom experience this and can you offer words of comfort or advice?
Answer: 1. We now understand why the Torah states 36 times: Do not oppress the convert. It is obviously forbidden to vex another person. So when we read over and over again "Do not oppress the convert" we think - we understand, enough already. Now we see that Hashem was correct in repeating this idea. 2. There is a new law that a Beit Din cannot nullify a conversion and only the Chief Rabbi has this authority. We hope that this will help to solve the problem.
