I only summited police certificate of no criminal record from China. I hope any additional finger print check (i.e. if they ask) won't delay the processing time for Provincial Nominee Permanent Resident.
Thanks very much for your info I already applied one certificate of no criminal record at Winnipeg Police Headquarter. They told me it would take 3 to 4 weeks. I am thinking that when I receive the certificate, I should send it to Buffalo even they haven\'t asked me for any further step.
