How long does it take to check the background of Canadian spouse immigration?

About 3 months, mainly call the notary office to verify whether the notarized documents are true, and whether there are loopholes, blanks or suspicious places in the materials you prepare. In that case, they will investigate. Not everyone will investigate. If everyone wants to investigate, they won't be busy ~ ~ hehe, so when applying for immigration, we should mainly find a reliable immigration company to help you, so.
