what if it was a language challenge, like it not being ur first language and you struggled with it etc because of X,Y, do you think that in itself is a strong enough example to expand upon?
Honestly - not really enough for it to be just about it not being your first language. That will be the case for most people moving to another country.
But it’s really talking about your experience rather than the facts. For instance, moving to a country with no knowledge of the language is very different to it being your second language. Living somewhere with little/no access to the things that were your day to day norms is very different to moving to a country with a very similar economy/society to your home country.
It therefore could be a good answer depending on your circumstances, but it’s generally one I have seen a lot and most times it doesn’t really feel too challenging it the way it is described.
