Hi
Hi there, for your information, my SDS application from Vietnam is now in Edmonton not in Ho Chi Minh, I know this since I sent email to the embassy in HCM they said they could not do anything because Edmonton is processing my application.Different processing offices, different format. But I think now that IRCC had time to sort out processing issues and the format, they have updated letters from Approval in Principle to "Moved on to the next stage" which still gives them to option to refuse an application. Because AIP means that they can't refuse you on the grounds of eligibility. Applications are distributed across different offices meant, a person sitting in Edmonton can't actually verify the eligibility AND admissibility of a student living Pakistan or India. Similarly few applications were routed to Ho Chi Minh or Beijing, they cant make a decision for other countries students based on the documents provided, since they haven't dealt them in the past. That may have been the reason that IRCC has updated processing and letter to just send out "Moved on to next stage" and let the actual Visa office dealing the country finalize the application. A lot of VACs are now operational around the world so they have the option to assign the applications back to the Visa Office for processing.
Seems like, CPC Edmonton/Ottawa are just checking basic eligibility, for example, all documents are uploaded and available, nothing is expired or out of line, student met SDS or Non-SDS category requirement etc.. proposed study plan in-line with past study and or experience etc.. Based on this, they may just add internal notes for the actual Visa officers to look at when reassigned to them.

All of these thoughts are my personal understanding of the process, there's a complete 100% chance that I may be wrong about these. Do not take my words as the words of IRCC. It's just my experience and understanding on the visa process after dealing it for different applications for number of years now.
