Answers to Questions by Yair Davidiy
According to Jewish law, is it possible that I am not Jewish?
My Father is Jewish and my mother converted to Judaism in Israel. I know there are strict guidelines as far as legitimate reasons for converting. She recently confided in me that she converted mainly because it made it easier for her to stay in Israel. What is my status now according to Jewish law?

Answer:
I am not an expert but I live the life as well as I can and I am acquainted with some of the sources.
Based ONLY on what you said I would say that it is 99% certain that you are a kosher Jew as far as the halachah is concerned, like it or not.
When your mother converted she knew what she was doing and willingly or not she acquiesced in principle to the commandments. That in a de facto sense is sufficient.
The Talmud says we choose to be born as we are. You chose to be what you came into the world as. You are suited to be yourself. Live with it!
Judaism is not bad. It can be very good. It may not be perfect but it gives more, and asks for less, in the long run, than anything else in the market. Make the most of it while you can!
