I am a new immigrant.

Don't worry, take your time. I don't understand some things you said. You said your girlfriend is Canadian, so aren't his parents Canadian? Because you said, "His parents emigrated, and so did she." If you are already a Canadian, is it necessary to immigrate? I have been puzzled about this for a long time.

Personally, I think it's better not to cheat. If the Canadian government does a background check and finds you cheating, it will definitely refuse the visa. This should be recorded in the file. You can't enter or leave Canada for two years. Even if you continue to apply for a Canadian immigration officer after two years, you will still care about your bad record. So, you might as well try to keep your girlfriend's heart now. When you are old enough, get a marriage certificate immediately, and then be a husband and wife reunion immigrant.

I wish you happiness.

I understand this time. At first, I thought your girlfriend was born and raised in Canada, but she immigrated from China. What a sweat. Investing in immigration ... Your girlfriend's family must be rich. Sweating again.

Your question is troublesome. You are not qualified yourself, and you can't get married yet. How many months before you turn 22?

Before that, I think there is no other way but to try to keep your girlfriend's heart and get her parents to agree to your marriage, because even if you go on a semi-tourist visa, you have to prove that you can pay for your round-trip fare, accommodation and other expenses in Canada. Unless your girlfriend's parents are willing to bear all the expenses you need during your stay in Canada.
