FWIW - My lawyers said renewing your TN Visa, when you live in the States is expected to be difficult - as opposed to living in Canada, and crossing the border every day for work.
My company heavily suggested I switch to h1b simply because they expected my TN visa renewal to be denied (I am now on a h1b1)
