It suggests to me that she is using the term 'asylum seeker' to hide behind to get an easier life.
Sure, there are genuine asylum seekers, but by and large they go to the first country that is safe, and close to where they are born. The type of people who will return back to their homeland once the imminent threat of danger has passed.
