Gloria had her interview this morning and was approved! It took about 90 minutes. She was not asked about vaccination (she is vaccinated of course!). She was also not asked for the updated tax returns she brought even though her case has been delayed so long (submitted documents in 2019, DQ'd Dec. 1, 2020). The officers she talked to were very nice to everyone, by the way, and they seemed to be fully staffed at about 8 officers. All in all, a good experience after the very long wait.
We want to thank @Hawk Riders for putting this thread together, and all of the kind people we've encountered here. We learned a lot of important information from all of you!
Our best wishes to all who are still waiting -- hang in there, things are finally speeding up!
