I'm Belgian and currently studying in Belgium. I got accepted for a 3-month internship in a government company in Hong Kong. Apart from the 3 months internship, I plan on staying one month and a half longer just for holiday purposes. So some questions:
1) Will I have a work visa or student visa? Is this only for the 3 month period?
2) If it is a 3 month-only work visa, can I just re-enter from Shenzhen of Macau to get a tourist visa?
3) Supposing I get a 3-month work visa, can I buy a two-way fly ticket with 4 months and a half between arrival and departure?
