Why do I need another Labour Market Impact Assessment if I just got one a year ago?

A Labour Market Impact Assessment (LMIA) is a document an employer may need to get before they are allowed to hire a foreign worker. The LMIA is valid for a limited time. If your employer would like to keep you for a longer period, they must apply for a new LMIA. Employment and Social Development Canada / Service Canada will make sure there are still no Canadian citizens or permanent residents who can do your job.
