He was treated for drug abuse in 2009 and is now preparing to immigrate to Hong Kong. Will the file follow me to Hong Kong? Is there any way not to follow to Hong Kong?

Hello! Well, immigration to Hong Kong requires a certificate of innocence. If you have a criminal record, you will be refused a visa. We can consider emigrating to other countries, such as the passport country project: Saint Kitts, which has no diplomatic relations with China. If you have a criminal record, it is generally acceptable to say hello in advance. You can get a Saint Kitts passport by investing $400,000, but it will not affect your China nationality. Or consider Malaysia. Now you can get a Malaysian passport for 750 thousand RMB, and you don't need to provide a certificate of innocence to apply for an immigrant visa in this country.
