Social Insurance Number (SIN) is a nine digit unique number assigned to individuals and is issued by Canadian Government. It is primarily used for financial, employment related transactions and tax reporting purposes under Section 237 of the Income Tax Act. If you are a temporary resident or a permanent one above the age of 12, a SIN is essential to work in Canada and to avail the benefits and services from Canadian Government. Your SIN cannot be used by anyone else and has to be protected to the most.
SIN For International Students
International students are eligible to apply for a SIN if they are planning to work in Canada. Having said that, SIN alone is not enough for an international student, but they also need to be “eligible” to work in the country. The SIN can only be applied for after the student is present in Canada as they need to get the study permit at the airport or at the border Post that, they fill an application form (NAS-2120-(05-04), which can be downloaded from www.cic.gc.ca or obtained from International Student Centre Office (An application form is not required when you apply in-person application at a service Canada centre). Do note that there is no fee levied for applying for a SIN.
The SIN for international students, start with the number “9” (code for temporary residents/ foreign students etc), which is an indication to the employers to make them aware that it belongs to a temporary resident in Canada. One can apply for a new SIN in case one becomes a permanent resident from a temporary one. SINs which begin with 9 are usually different than the SINs that are issued for the permanent residents/Canadian citizens as they hold and expiration date which usually matches the date on the holders work permit. These SINs are deemed invalid unless there is an expiration date on the card or the date has not passed.
