Adding , Walmart won’t go thru the time & expense in applying for a LMIA for a foreign national when there’d be ample supply of citizens /PR that could do the position
Sorry that you are unemployed but if you are uotside of Canada it is virtually impossible to get any job offere from outside of Canada unless someone has very unique skills not readily available in the country. Unfortunately jobs at employers such as Walmart would not come into that category.
Other than that there are no jobs or employers on this forum
