US Immigration from Trinidad and Tobago

Ok guys I need all the help i know some of you will be scarsatic and even throw in some constructive criticism, so here is the deal. I have been a PR since 2012 and unfortunately have been outsie the country more than I was supposed to be due to uforseeable circumstanences. I applied for citizenship in oct 2016 and I had my interview in June 2018. As you all could guess, it was denied as I was not physically present in the country less than half the time as I required, but the officer who interviewed me also requested that I should have my husband's naturalisation certifcate. We had used is passport to initate the process in 2011. I have felt defeated hpwever I have decided to give it another try I filed again for the n 400 in jan 2020 I have not been outside long, from 2018 to 2020. In 2020 Feb I travelled to trinidad and the borders were closed still are if you wanted to leave the flights were pricey hence I waited till it was reasonable I arrived in jULY 2020. The other thing is my husband's ex still has his naturalistion certificate do I really need it if I am filing based on 5 years as a PR? A new one is $555 which is like crazy, thanks for your help

My wife visited me in the US before the I-130 was approved. We are going through consular processing. She was approved while still in the US. However, her country s borders are closed so she is unable to go home in time for the Interview. We do not want to adjust status. What can be done?
