Callum,

It really depends on nationality. I'm not sure if you're American, but I've heard that it's harder for Americans to turn visas over in Hong Kong than elsewhere. The government put some extra restrictions on visas following the financial crisis that you might be running up against, this following other restrictions imposed after 9/11 when the US apparently started fingerprinting foreign nationals.

Regulations are unevenly enforced, so it may also be a question of where you are and what sort of guanxi your school has. I'd say that if you have a school willing to buy the plane ticket, don't worry about it and enjoy the trip home.

There's a holiday early next week, but if you need to reach us in Beijing feel free to give us a call. And if your time is running out you may want to try extending your tourist visa in-country. It is theoretically possible to turn over tourist visas for another 30 days in-country by visiting the local police station and asking. Or maybe the Entry-Exit bureau. I've never done this myself but have heard of it being done. Just tell them you're a tourist and want more time to tour the Yangzte before returning to Hong Kong.

Cheers,
