I would rely on advice from an attorney in Maryland. But, I tend to think that neither of you can hold the other liable because you were both at fault for the accident. If you have homeowners or renters insurance, you may want to notify them of the potential liability claim.
I am very sorry to hear about this. Talk to an immigration attorney familiar with removal defense about getting a bond. There are a number of issues that might benefit your husband that are too involved to get into here. I wish you and your husband the best of luck.
Many firms will consult with you about this for a relatively small consultation fee, including my firm. Even if the firm is not local, they may use skype or simply speak on the telephone.
If you send your wife out of the country, she will likely be subject to a 10 year bar from re-entry. I would normally not recommend that! I think the odds discussed by the attorney you consulted with may be more in your favor. However, I do not know why there was a removal order. Did she commit a crime? You need to speak to another attorney and get another fee quote.
I like my colleagues idea of applying for a B2 in the interim. But, before making any decision, ask to speak to your employer's attorney to discuss the RFE and the odds of the extension being rejected. Tell the attorney what you are considering since you do not want to take any action that is inconsistent with your intent to stay and work.
Congratulations on the pregnancy!
You will need to prove that your marriage is legitimate and it wasn't done to benefit your wife financially or to help you get a green card. I understand that money is an issue for you now, but I strongly recommend that you speak to an immigration attorney before you do anything. I expect the USCIS will be suspicious of everyone's motives in light of your wife's financial problems.
I agree with my colleagues. An experienced immigration lawyer can help you prepare for the interview and even attend with you. I strongly recommend that you consult with counsel. It is money well spent considering what is at stake.
I am concerned about why you not only entered the US with a false name, but continued to represent your name falsely to the government during the green card and citizenship process. You need to consult with an immigration lawyer. You may be able to fix this, but I would not do anything without getting good legal advice, more than you can get in this forum.
