A foreign national seeking spousal sponsorship to Canada faces a highly complex legal process, regardless of whether the application is submitted domestically or at a Canadian embassy or consulate abroad. The spouse, common-law partner or conjugal partner seeking to immigrate to Canada must be sponsored by a Canadian citizen or permanent resident, who must also submit a sponsorship application in support of the foreign spouse.
An open work permit is a work permit that is not job-specific. It allows your spouse or common-law partner to accept any job with any employer. If your spouse or partner gets an open work permit, it is normally valid for the same period as your study permits.
