How long will you stay there?
In general, you can apply for a Visit/Transit Type to visit HK. To apply it, you need to prepare your valid passport, an application form, a recent taken photo, your round trip tickets to HK, your travel plans, your bank statement and an invitation letter from your cousin. You are suggested to mail all your documents to HK Immigration Department for applying.
