What should I do if my visa for studying in Canada is rejected? Can you sign it again? How long will it take?

Don't worry if you are refused a visa to study in Canada, because you can sign at any time as long as your overall binding force is improved.

Because it is not terrible to refuse a visa, as long as your binding force is greatly improved compared with the last time, you can pass it completely, instead of refusing a visa several times as mentioned on the Internet.

Refusal only means that your binding force can't reach the historical stage required by the embassy. Just like when we took the TOEFL, we got a perfect score of 100 and passed 60. Last time you refused the visa because your binding force did not reach the minimum passing line of 60 in the embassy, so we should try our best to improve our binding force and raise our binding force score. As long as the binding score is improved, we can sign it at any time.

It's like we failed in the college entrance examination, then went to a cram school, then went to a cram school after the failure, and finally got in.
