so for example if we go to the border with the baby (canadian citizen) and we need to return to canada because my baby still small and she is taking medical control and treatment they can refuse the entry?
one last question:
my employer apply the lmo 1 week ago.
I need to apply for the extension visitor visa? or can i wait for the lmo answer and then apply for the work permit?
If you don't have an approved LMIA by the end of November, you should apply to extend your visitor visa. Otherwise you will lose your status in Canada and will have to apply for a restoration of status in addition to the work permit once the LMIA is approved. You should avoid going out of status since this may make it more difficult to get an approved work permit.
Note that many LMIAs do seem to be taking several months to be approved. So it's entirely possible you won't hear anything by the start of December.
them me and my wife we are going to apply for the extension of the visitor visa this week because they says that you have to apply 30 days before your status expire.
its ok if I write in the purpose of my visit: OTHER and REASON: baby born canada premature medical control or better select TOURISM?
