In addition to the information in the previous responses, it sounds like the attorney you and your spouse have engaged recommends that he be hired to represent you at the interview. If you are reluctant to follow your attorney's advice, I strongly recommend that you schedule a meeting to let him know you have lost confidence in his advice and to ask him to respond to your questions. As others have replied, the details you mentioned do sound like ones that would make it highly valuable to have an attorney provide representation at the interview.
Additionally, in assessing the wisdom of paying the incremental cost for representation at an interview, one must make a decision about just how important it is to succeed in the case. For some people, this is nearly the most important matter in their lives, for others, being able to remain in the U.S. as a Permanent Resident may be a far less crucial matter in their lives.
