Hi there:
my mother and younger brother are landing to toronto in Sep 04. i have
following questions for an expert reply:
1. since i sponsored them, is it compulsory that i should be present
there. around their arrival i will be away on business trip out of
canada.
2. i am middle of address change from brampton to windsor. should they
give my barampton address or windsor. by the time, they arrive address
will be windsor (but i will not be able to inform CIC prior to that).
if they give windsor address at the landing time, will it be ok.
3. they are bringing around $5000 plus list of items with them and
list og "goods to follow". would that be ok.
4. they plan to stay for 5 weeks. would it be sufficient to get PR,
SIN and health card.
thanks all for your reply.
