Am I overestimating how hard it is to emigrate?

Like a lot of folks, my husband and I are making a Plan B in case we need to get out of the country quickly. We're not planning on it, and we hope we won't have to. But along with our child, we fall into a few different demographic groups that could put us at risk depending on which way the wind blows, and we figure it's better to be safe than sorry.

My understanding is that a lot of the places we would want to consider going, such as Canada and many countries in western Europe, are really difficult to emigrate to. My husband and I both have graduate degrees, and I work in a very "transferrable" field, but I'm still pessimistic about the chances of being approved for emigration, for example, to Canada or the UK. Canada would be our first choice, for a couple of reasons, and I'm working on learning French because I heard that in a lot of provinces, your chances will be better if you can speak French (my husband is already fluent in it).

But I hear a lot of people talking about leaving the country like it's easy, which makes me wonder if I'm overestimating how difficult it would be. Am I being overly pessimistic and overthinking this, or just being realistic?
