hi
I have applied twice for Germany PCC from Canada and my experience.
1) Took attestation from notary near me and paid the fee, once using Remitbee app ( transaction fee $ 3 CAD ) and second time using TD bank global transfer ( transaction fee is $9 CAD) one difference among the both we can give infavour name / message in Remitbee app. while TD app we can give the message where we can give the details. ( when I applied using remitbee i have attached the transaction receipt ).
2) I have used DHL courier service to ship the application, it took three days for shipping the application to Bonn. ( -CA -> US -> Customs -> Belgium -> Germany- Bonn)
One mistake I did in the fist application, given my friend German address to avoid shipment delays/ discrepancies, which caused an issue that on the certificate friend address is printed. So better avoid the short cuts. First Applicaiton -> Sent on Feb 22 from Toronto CA, it reached on Feb 26th, Certificate was issues on march 10 and the certificate was shipped to friend address on March 18.
As friend's German address is printed applied second application and shipped on march 22th and document reached at Bonn on march 24th. Second application was issues on April 13 and shipped to Canada address on April 13th. It took three weeks to reach to Canada address.
Received the Certificate with Canada address on the certificate on May 4th.
Germany help desk people were good, they responded to email timely with patience.
