I can see a few options. Once it is time to file for the removal of the condition (form I-751), select the option "I am a child and can not file with my parent" I believe this is the second box at the top. You must explain what is going on..that your step dad wants you to change your religion, explain the whole situation in a statement. You could also filed a self petition under VAWA as an abused child. This is a very generous benefits, but the paperwork is quite intense. You should have an attorney experienced with this type of paperwork to help you out. (I actually would love to handle your case!). VAWA involves proving that your step dad is either a green card holder or a US citizen, that he is married to your mom and both your mom and your step dad lives together, that you are a good person (no criminal history), and that you are abused (Threatening with immigration benefits unless your convert to a religion you do not agree with, that your mother is also abusing you and is siding with him). Both petitions could be filed at the Vermont service Center, (no matter your locations) with a fee waiver request. Be very quiet about your intention. You should have an alternative address, such as a mail box or use the attorney's address. Both process are confidential, meaning that your step dad doesn't have to know about you filing these types of petitions (VAWA and I-751). He might learn if you tell him or leaves paper around the house. Good luck.
