Assumption is based on the fact that after a pre-arrival no one was asked for further proofs in regards their relationship. The first step was either one of pre-arrival, or request for additional docs, phone call, or interview. People who attended interview were sent pre-arrival within days, those who submitted additional docs received PA within a month or so, someone who got phone interview got it same day, and many received PA directly without any further information request in order to prove their relationship. If ever a PFL was issued after pre-arrival, it was due to other aspects such previous Visa refusals etc.
But, our concern is only about the timeframe elapsed in file processing. Either all applications must be cleared within 3-4 months , if not then everyone should wait for same 8+ months like NDVO. I am myself suffering due to this discrimination based on no idea what. I am in living in Canada for over 20 yrs and now I am standing in this queue like fools, whereas on the other hand, an international student who received PR last year, her spouse got PPR in 2.5 months time from Mississauga. I am not against it if anything good is happening to others, But its not fair. That makes me feel like a victim with no fault of mine, because I have also submitted all the required information along with the application. And if still something was insufficient according to the visa officer, they must get back to me quickly to ask for whatever is further needed. Making us wait for months on like idiots is not an appropriate way.
