Keeping this in view, how long after polyurethane can I wax?
I think you'll be completely fine with one week cure time. "Full cure" will not need air to happen, thus you'll be completely fine with applying wax one week after applying the poly. You could probably get by with less, but a week to be completely safe.
Apply only one thin coat. Then, remove any dust nibs with 1,500-grit sandpaper or a piece of brown paper bag. Finally, using a soft cotton rag or polishing pad, buff the finish to a high shine using automotive paste wax, photo below, which has fine abrasives that polish the finish even further.
