Hi am in canada presently with my family. what i will tell u is that do not leave ur job, come and land with ur family and make sure u do not stay out of canada in a 6months period. it is really not easy but what i will advise is to leave ur family here because u get ur canadian citizenship if u r physically here 3yrs after u land. so fo the sake of the kids let them be here with ur wife and u can come once in 3months to check on ttem, the only thing is that they will definetly qualify for canadian citizenship faster than u.my husband read geology from nigeria and came here to study petroleum engineering but things are a bit slow cause of the recession issue but will definitely pick up. or u can arrange wtih ur company so that u will be an expatriate and u pay ur taxes here in canada.wish u good luck. canada is a beautiful place to live and for the kids education but the weather is something else in winter. if u need an other advise u can mail me funke1968@hotmail.com then my husband can advise u more. goodluck
