Correct. Hong Kong is the correct country of chargeability so the process, particularly if an NIW-based green card is pursued, would be around two years based on current green card backlogs and processing times. The problem with TN status for those pursuing green cards is that because of the current backlogs, you might be in the difficult position of needing to travel or extend your TN while you are in the green card process but bot far enough along such that could get temporary travel authorization. You would not be able to travel or extend your TN.
