Hi, My TN status was denied by USCIS recently. I am planning to apply at a POE, most likely a border rather than the airport. Category will be Computer Systems Analyst. Can someone offer detailed guidance on what is involved in this? What documentation do I need to bring with me? How early do I need to get there? What questions are asked by the officer? Also I was planning on applying at Rainbow bridge or peace bridge- are there POEs that are better than others?
