I actually see something unexplainable LOL. its actually hard to be patient if I were you. Even for citizenship, I have seen many Dec 2019 applicants got invited for the test. Well, go to gym or find something to do, let ignore it. That all I would do if i were you.I hope so too. It is hard to stay positive when you see so many applicants getting processed even fro June end . i am glad for those people but this is way too much waiting 20 months and nothing no DM1 nothing for Main applicant ever since they are like the background check is happening i mean how much background check they need like it is been forever. I work every single day in COVID and now it is part of the life then they just need to work. My citizenship file is same way in 16 month nothing . So it is about being Unlucky
