FOSS is a list that canada has, concerning people they are watching for... these include those who have been denied visas in the past, or similar cases.
i went to canada before, but only via visitor visa... so i may have some entries with them. i would like to believe that "no history" is good news, or to mean "no history of bad record"... or just simply that i am not in the blacklist
i also don't have any idea what's keeping the local VO from proceeding with my application. and i cannot politely budger them since i'm still under 6 months timeframe, but i will still attempt when i'll hit my 5th month. i just fear that my file is way down in their priority cases.
when they see PCCs, usually they clear criminality. but security checks may take long coz it involves other agencies which are beyond CIC's (or even canada's secret service) control.
