RD Jan02,
Just what everybody said that RFE is a good thing and atleast somebody looked at your case.
It's very natural to worry about this. On April 2nd as you probably know that RFE was issued on my case. I was wondering, since i am in the same job but i have moved 5 times since filing I-485, maybe they would want to confirm my employment etc!!!
However, you'll be shocked to know that they only asked me for "original papers for medical" as the doctor had mailed the copies.
Now, it's not possible to get the originals from the old doctor, so today i went and get new medical done!!!
Let us know what your RFE is about, you never know until you get it..!!!
Cheers
