Work experience of skilled immigrants in Canada

You don't have to provide social security and tax bills, and immigration officials generally don't ask you to do so.

But if you provide it, it will be good for you, and the chances of signing it will be much greater.

The social security and work certificate provided are not from the same company, which is a bit troublesome, but you can ask the boss to make a written explanation and copy the business licenses of the two companies. It is best to notarize the business licenses. As long as they are proved to be the same boss, the problem will not be great.
