i know there are processes you must follow and not just any country will let you in, so what must someone look for when it comes to finding a new country? i might go to the netherlands because i wanna go there, but it may not be allowed given the circumstances. i ask because someone was asking what country should they live in and people were arguing over it.
You need to learn the language of that country very, very good. Otherwise you will stay a visitor, forever.
Exceptions from this rule are the few countries where your own language is already their first language.
Well. You need to learn it well.
