Being a 'lady of leisure' will provide her with endless opportunities to get a proper "feel" of what it's like to live in the UK. It'll also enable her to meet lots of different people ... and build up a circle of friends in her new neighbourhood and beyond.
Moreover, the spare time can be utilised to plan ahead ... and even give her somes as to the type of work she'd like to undertake once her Further Leave to remain has been granted. I wish her well!
