Do TN visas from let's say UNIVERSITY OF WATERLOO get an rfe when apying for H1B ?
No.
What TN visa category? You'll more likely find people with similar experiences if you're specific on role and visa category. Also consider going directly to greencard assuming you were born in Canada it at least a non backlog country. You get a six to nine month travel restriction where you can't leave the country due to TN being a non immigrant visa but if you can stomach not going home for most of a year that avoids the h1b lottery and saves at least a year (and more of you lose the lottery).
Hello fellow UWer, do you mean the TN itself or when you transfer to H1?
H1b has nothing to do with TN visa.
Do you really think someone on Blind will be able to speak for the USCIS?
Or rather a random officer who has their own discretion to issue one
