It's frowned upon but I know of several JW's who have studied law, either through Uni or as adults. All were considered ok but had to justify their actions and suffer snide remarks at meetings. Remember plenty of dubs work full time so it's a bit easier to justify switching to full time education if you still do the same FS and go to meetings and depending on how popular you are.
Come to think of it one of the sisters was married to a loser JW, got a scriptural divorce and then did her law degree. She had been pioneering most of her life, was quite stunning and intelligent so I think some local elders supported her (likely in the desperate hope she'd fall for one of them eventually - they were disappointed - she married an elder overseas).
I know that when you're no longer in it, there are so many actions taken by JW's that are hypocritical. She may well be spiritual or it could be part of her plan to fade - I guess approach with caution.
