I also want to apply for skilled immigration to Canada. I am also an embedded software engineer. How do I apply?

Download the form from the embassy, fill it out as required, prepare the materials according to the list, pay the application fee and send it to the embassy.

But I advise you to give up this idea. First, skilled immigrants in Canada now have strict requirements and few indicators; Second, your occupation is not on the shortage list and it is difficult to approve; The third is whether you really want to leave the present environment from the heart. It is not easy to start from scratch.
