Please note that Bachelor degree from abroad e.g US, UK, Germany, France etc... does not really help in achieving great success. What really matters is Masters or PhD degree from these countries. As the cost of studies in these countries is really high, I would advise you to complete your bachelors degree here in Pakistan and then go for MS or PhD from USA or any other country. This will really make a huge impact on your career prospects and you will be much more focused. Moreover, by that time you would be old enough to cater to the problems of living abroad and settling there.
At this time, it is really not a good option.
