According to what I had read, there is a reason behind it (sorry, I don't remember the source anymore). They asked for the $ 550 fee upfront along with the sponsorship application, however, they did not ask for the PR application forms/documents for the sponsored person (for whom, the $ 550 fee was paid upfront). There had been some cases where there was a problem with certain applicants and CIC had been challenged from a legal point of view, i.e., for charging fees ($550) for applications that had not been received. That's why they changed the rules for parent sponsorship in July, 2011: After this date all sponsorship applications had to include both the sponsor's application forms and also those of the person being sponsored. And they decided to ask for the PR application forms and additional documents for the parents for whom applications were received prior to July, 2011.
