Can I go to Hong Kong with my passport only? Urgent. . .

You can't go to Hong Kong only with your passport.

Shenzhen people say that as long as they have a passport, it means making a fake ticket and going to Hong Kong through Hong Kong. If you have a valid foreign visa on your passport and an air ticket from Hong Kong, you can use your passport to enter Hong Kong and stay in Hong Kong for 7 days, but then you must go abroad.

Otherwise, if you go back to the mainland directly, you will be at the Hong Kong Immigration Department (not the Customs! If you leave a bad record, that is, your passport is DT, and you want to enter Hong Kong in the future (even if you really want to transit through Hong Kong and fly abroad from Hong Kong), you will be questioned when you enter the country, and you will not be given as much time as seven days.

If you are DT again, you are denied entry to Hong Kong for the third time. An expired Korean visa on your passport is useless.

If you work in Shenzhen and have a Shenzhen residence permit (more than one year), you can apply for a Hong Kong and Macao pass and a Hong Kong endorsement directly in Shenzhen, otherwise there is no other way.

It is the border inspection department, not the customs, that checks your passport and visa and decides whether you can enter the country. The customs checks things, not people (documents).
