Canada visa officers evaluate a variety of factors when processing visa applications. The validity and integrity of the applicant's travel documents, such as their passport, are scrutinized. They also assess the applicant's financial ability to support themselves during their stay, the purpose of their visit, and if the applicant has a criminal record or poses any security risks. Furthermore, they verify if the applicant has ties to their home country that would incentivize them to return, like family, a job, or property ownership.
