I'm opting for the brief version ...not so extensive as what my original comments were going to be.

Immigrant:  a person who comes to a new country, region, or environment ...particularly with the intent to settle there.

We all have much more familiarity with some areas than others. We likely are more familiar with the environment we live in, and less familiar with those we've not yet had the opportunity to visit.

We often think we know what we don't like, yet may not know what we would like ...though we may have some idea about it.
