can you please assist me for requirements if i want to visit my mother in hong kong

April, as far as I know, Philippines passport holders can enjoy free entry to HK for a stay of no more than 14 days. Thus, you don’t need to apply for an entry permit in advance.
But if you want to stay longer, you can apply for an entry permit as dependants. You need to provide the following document: copy of your passport, the application form, your recently-taken bareheaded color photo, as well as relationship certificate such as your birth certificate or family photos. The application can be submitted by your mother to HK Immigration Department directly.
