ICE does detain people with final order of removal during interviews sometimes. The main question you need to ask is can your I-730 even be granted by the USCIS with a final order of removal on your record. The problem is that USCIS cannot grant benefits when the final order of removal exists or even when the applicant is in removal proceedings. In such matters, the first thing to do is to re-open the Proceedings with the immigration court and then terminate them administratively. When the removal order goes away, US CIS can grant the petition. Alternatively, you can ask the judge to grant you benefits.
Your story is very confusing. First you said that you were deported 8 years ago. Then you said that you were not in the US in 2014 but now you are here. Did you re-enter after you were deported? If yes, how did you re-enter? Was it an EWI? Also, you mentioned that your husband’s asylum was granted just 5 months ago. A much easier way would have been to add your name as a derivative before the petition was granted. Your lawyer could have done it during or just before the hearing.
Edit: Since you re-entered after being deported, you have inadmissibIity under 212(a)(9). Hence you will need to apply for a waiver under 209 (c) as well (form I-602). its usually granted for Asylees and derivative asylees.
