Yes . I tried applying for N400 a few times and it got denied and I received letter stating it was due to moral character and I never understood so this last time my lawyer got involved and file and it got denied again and that is when the letter was sent explaining that my 751 shouldn’t got approved since my first marriage ended so technically they saying that they are going to terminate the conditional residency. Not only I was not eligible for citizen but now my residency is in question . They do have all of the documents for my application on file still . The problem we relocated to LV and going trough a new ins jurisdiction and we filed everything in Ohio back then and I don’t know how to proceed . I told my current husband that we may need to get another attorney . This is a lot and very stressful
So your jointly-filed I-751 was approved in error, since you were already divorced. It sounds like they basically reopened that I-751 and denied it.
I think you have two options:
1. File I-751 again now, on the basis of divorce (basically, what you should have filed in the first place). Although it has been many years since your 2-year card expired, there is no time limit to file Removal of Conditions on a waiver basis (i.e. any basis where you file by yourself, including divorce). You can file Removal of Conditions on a waiver basis at any time up until you are removed. Even if you were placed into removal proceedings in immigration court, you can still file Removal of Conditions with the immigration judge. You should be able to get I-551 stamps while your I-751 is pending. And when your I-751 is approved, you should be considered to have been a permanent resident the whole time.
2. If your current spouse is a US citizen, file I-130 and I-485 for Adjustment of Status to get a green card from scratch. Although there is a rule that conditional permanent residents cannot apply for Adjustment of Status again, Matter of Stockwell ruled that if the person's conditional permanent residence is terminated, this bar no longer applies, and they can apply for Adjustment of Status. See
7 USCIS-PM B.7(G). Note that if you go this route, your spouse will have to do an I-864 Affidavit of Support for your I-485, and it will mean that when your I-485 is approved, you will be considered a permanent resident only starting from that point, and have to wait a few more years to naturalize.
