There's no issue with moving from a TN to a green card; the process just needs to be managed carefully and all this really means in the end is coordinating the timing of the filing after deciding on the green card path (that is, whether through USCIS or a US Consulate).

Something that's never been clear to me. Suppose you file the I485 and show immigrant intent but the application falls through; how long do you have to wait before you can reenter on a TN visa?
