Actually, it depends a lot. What do you want? A better career? Or a good family. But it does not mean that if you go to US you can not have a good family. Yet probably this chance is smaller. Just in terms of career, the main factor you would like to consider, I do not think age is a big problem. Your score is much more determined by your effort rather than your age or physical situation. It is very normal for 40+ people to take master/doctor programms, maybe part-time, in HK or some developed areas. It is not so late to start a new career in 30s. Maybe your former working and educational background is your advantage to find a good job. Better late than never. So if you do make sure you will get offers from prestigious law schools and have prepared to spare no effort to get high scores in your study, which both determine whether you can find good job after your graduation, and more importantly, do not care your individual problems, I mean single woman, then just do it. Balance both side, list all the advantages and disadvantages, then choose the one with less disadvantages. Maybe one thing you need to reflect on, what does a better career, even top career, mean to you? Happiness? More money? Or something else?
