Consular officers of Chiense embassy had visited Adelaide on Jan.28 for passport service, and no more notice has released yet.

Hi Ms Enid,

Thanks for your response.
With regards to your final paragraph, mentioning that Chinese Consular officers visited Adelaide on 28th January. Do you know from whom we can find out more about these visits? For example, some of the things we'd like to find out are who arranges/organises the visits, which location in Adelaide do the officers work from, what are the fees and when is the likely next visit?

Thanks.

Oh, for visit time, you'd better contact Chinese consulate. visit of consular service is periodic but to didfferent cities, I am not sure if they will have one in near future in Adelaide. Sorry for that.
