Immigrate to Canada and log in for the first time. How to book a flight? Can I book a return ticket?

Of course you can book a flight. You can book a round-trip air ticket. I don’t know what kind of immigrant you are, whether it is technology or investment. Some immigrants need to undergo immigration supervision. It is very important to check clearly on the Canadian visa page of your passport whether it is SINGLE ENTRY or MUTIPLE. You have to read clearly whether the validity period is on the visa. Anyway, you need to read all the contents clearly on the Canadian visa page, otherwise it will be very troublesome if you make a mistake.
