Hi! I am a U.S. Passport holder and I am visiting Hong Kong the week of Aug 22nd.

I'm hoping to take a day trip into Shenzhen. I've visited Shenzhen before and was able to apply for the temporary Visa at the Shenzhen border quickly for same-day access. Is this still available or has the temporary visa for U.S. Passport holders been removed?

Also: How's the weather nowadays and where/when should I party?

Thanks!
