Thank you Kath1236 for your reply.
1. could we landing Canada on weekend? which bridge is easier? Peace? rainbow? or others?
2. why do we need to rent car to landing Canada?
3. if we apply SIN, does this mean we have to do tax return at end of year?
4. why do we need to prepare import list if we do not want to stay Canada? we may go back later.
5. using H1B landind, is because we can use hte 30 days return to US policy, is it ture?
thank you!
