How long does it take in marriage immigration and Canada?

Generally, the time for approving the guarantee is 1-3 months, depending on whether the materials you have prepared are sufficient. It will be faster if there are enough materials. If the materials are approved in Hong Kong, it will take six months at the earliest, and there is no need for an interview. If the materials are not good enough, the age gap is big, and the difference between China and the West is so big, it needs to be interviewed and reviewed and supplemented in more detail. It's possible in two or three years.
