I would like to know wether my passport is blacklisted or not?
You have to contact either the Bureau of Immigration or Foreign Division of Ministry of Home Affairs to get to know whether your passport is blacklisted or not. The 'blacklist' of those who reportedly violated visa rules or engaged in ‘undesirable’ activities are part of these departments. However, it is not sure whether they will provide the required information or not.
Contact details of the nearest Bureau of Immigration office is provided here.
