To Honk Kong from US, anybody has advise?

Check with their equivalent of the Board of Nursing to find out requirements.
You will also need to deal with immigration for working there, usually handled by the employer.

There is no reason that it can't be done, but be aware that they may require you to write the exam in Chinese. Are you fluent in it?

Here's the link to some forms.

You more than likely will need to speak Chinese to take their boards. Same as if someone from there comes here to work, and in any other country in SE Asia, etc. The only way around that is to check out some of the US bases there. That is your only other option.

You need to be licensed in Hong Kong to work in any facility other than on a US base.
