Spouse Visa has become a popular visa category in a decade. The most popular countries to study abroad among the students are Australia, Canada, UK and New Zealand as all these countries allow international students to invite their spouse to join them during their stay in a foreign country.
However, every country has their own immigration criteria to allow the partner to join the main applicant.
In Australia, the spouse can travel with the main applicant only in case of going to study master degree, same goes with New Zealand and UK. Beside that, in Canada spouse visa can be applied after a certain time period of main applicant's visa grant.
