I sincerely ask you about immigration, and I hope someone can help. thank you

If you don't want to invest in immigration, I suggest you don't consider it. First of all, because the immigration policy abroad is very tight, especially for those with skills and experience, foreign countries do not agree with these people. The reason is that these people often go to Canada to make money rather than really provide technology, and it will make their locals lose many job opportunities (which is very important). It is difficult for me to immigrate to Canada now. Every year, many people like me waste their time and lives here. You should develop well in China and provide a better environment for your children. Then you can send your children to study abroad in the first year of high school, so that you can adapt early and immigrate easily. This is the best way. I hope it works for you.
