Honestly, my own opinion is if it is affordable for your situation, of course go to the States and try some new things! You can always come back to Hong Kong in the future if you really don't like living in the States, but at least you can keep yourself have alternatives. If you now settle everything in H.K., you may not be able to change it after few years.
It sounds like you don't even have a clue on how the American education system runs, you'd better consult with the agents and get more ideas and options.
