I beleive bdkhyd, because it happened to me also.
I talked with tier-1 only for almost 1/2 hr, pestering her in a nice way, to see if I can get to tier-2. But couldn't. I couldn't even convince her to generate an inquiry, because my case was only 18 months old.
And after after 1 week, I received rfe. I forgot to sign the medical form. And they also asked the regular stuff.
They received my rfe on Nov'20th, and no updates yet. So I am thinking of calling them again and see if that would trigger a approval.
There is nothing wrong if you give it a try. . .
