If you are already a senior student, you should make your decision as soon as possible. It is a good thing that you have some independent thinking about whether you should go aboard instead of simply following your parents' words. If your family can afford the expense vey easily, it is not a bad idea to experience a different life and culture and it may benifit you in the long run. But if that's a differnet case, I personally think working first and seek future opportunity is not bad. (Of course it is very likely that after working you lose the passion of going aboard.
