hello i have a short over stay of 4days in china, because my visa was expiring on Friday so the same day i decided to go to Hong Kong to avoid overstay.. unfortunately the Hong Kong Immigration did not let me in and they deported me back to china.since it was weekend , i could not go to the Chinese immigration.. now i have decided to go there on Monday to ask for extension to go back to my country..i would like to know if they will put any stamp on my passport that will stop me from Applying for a Z visa? if yes is changing a my passport a solution??
