I am extremely sorry that, at my previous quote has one mistake. it should be Fixed deposit instead of Provident Fund.
anyway, Answer-1: it will be better to show ur provident fund with ur PF(Proof of Fund), then they can understand better that u r doing job as u claimed point. because somebody doing fraud & misleading regarding job document. personally i heard from some people, sometime they investigate regarding job as u provided them the document by there local embassy. However,it will not count as a PF. u have to proof PF BY "Fixed deposit", "Term deposit" or "Time Deposit". but must should be the mature for 3 months before your application submission.
Answer-2: They will not check it, because this will not support ur PF(Proof of Fund). but it will increase strength of ur job evident. if any reason, they suspect ur job evident then this will be support u to stay in boat. SINP only try to see ur liquid money in bank & there maturity. another thing is that, u always try to show ur liquid money more than there requirements. say, for 3 people (u,spouse & kid), u have to show minimum CAD $18500, but u try to show CAD $25000-30000 (THIS IS NOT MANDATORY BUT IF U CAN), This will increase probability of ur application strength. Best of Luck.
yes u can send any document by e-mail & they will update accordingly. remember that, Now SINP is very busy & passing the rush time with EE & OID both. as well as they will nominate 1000 application for refuge at next two weeks. so, from the forum we found that they are rejecting/returning the file due to few mistake by applicant without give any chance. but this is depend case officer to officer. so , if anybody missed any document/s, then they should send before they asking. Best of Luck.
