When applying for a Canadian visa, why are these cases refused?

After all, Canada is a developed country and has a certain probability of refusing visas. Even if the information is good, it will be rejected. Visa officers mainly examine the following factors:

Have you ever been to a developed country like Canada? For example; Europe, Australia, Japan, Canada, and other underdeveloped countries such as Singapore and Mattel have no exit records. The visa officer will think that you have returned to these developed countries with the same level as Canada, and you should return to Canada. The chances of staying are slim.

What about personal assets and cash flow? For example: personal savings, whether you have a house or a car and other information that can prove assets, the visa officer thinks that rich people rarely stay, and there are enough assets to prove that you have the economic ability to go to Canada.

Regardless of whether there is a stable job or not, the visa officer thinks that people with stable jobs will have less chance to stay abroad or work abroad.

Whether you have a happy marriage and family, such as: getting married and having children, parents alive, brothers and sisters, and a large number of relatives, is the best family information, because these are all factors that you deserve to stay. There are so many families in Canada, why do you stay abroad alone?

Do you have the language ability to go to Canada independently? You can't just have money. What should I do if I don't understand the language and get lost? It's dangerous if you have any difficulties or get sick unexpectedly and can't even express yourself.

If one or more of the above information is not good, it means that your immigration tendency will increase and your visa pass rate will decrease.
