I am preparing to graduate from college at the age of 23, but I have no job and rely on my parents. Parents 1 year ago applied for investment immigration in Canada. Can I still go with them?

You are their child, of course you can go with them, but I think since you graduated from college, you should figure out how to go in your future, instead of relying on anyone or blindly. Dependence will make people lose their fighting spirit and positive attitude towards life. One day you have to rely on yourself. As the saying goes, you should prepare for your goals in your twenties. If your parents support you for so long and so hard, I will never depend on my parents again after graduation.
