How to apply for a Hong Kong visa as a U.S. Solider in South Korea??

Hi, you have to make an online appointment first at CVASC's website (please choose the right office according to your residency). The form can be filled online as well. The office may accept application by post, so that you need to visit their website for details. BTW, you can also entrust others if you can not visit the CVASC in person.
