hello rubaiaat!
the canadaian immigration will nominate u 25 points for ur educational background if u have 17 years of education. i mean primary level:05 high school level:05 secondary leve:02 years bachelors {4] years :04 years and a masters :01 year thats summed up 17 years of education. they will award you 25 points on that ground. but as u said two bachelors degree at the same time implies that any student can take two bachelor\ degree but they will not be awarded double points for these two degree at the same time. suppose , i did 2 years bachelors [pass course] and a BA[Hons], in that case they will only consider one of the two degrees. this is perhaps very true for bangladeshi candidates.
you must have at least 1 year full time experience in the last 10 years... which means that it is not necessary or mandatory that u must be in the position continiously. YOU MAY QUIT THE JOB OR YOU MAY GO ON A VACCATION . it is not their concern, the fact is that you worked in that position for those period, so u can apply without any hesitation. and read the literature at www.cic.gc.ca/english ie: WHO CAN APPLY?
dear, carry on ..
best of luck
