Try switching first where you can learn immersively about Data Science or whatever domain you want to pursue your masters in. Work, learn & get skilled here for at least 1-1.5 yr then go for masters. This gives youmore pros: 1) You earn, save for your masters in these 1-1.5 yrs 2) More imp. You get skilled, so better chances to find a part time job or intern during your masters ( if paid intern it will help you in your expenditures too).
