I have a friend (here in the U.S.) who is an accountant, a CPA. He has one of the best work/life balances I’ve ever seen. He is able to take a considerable amount of time off work and has enough money to enjoy that and still be financially secure.
He says that he went into accounting (mainly doing taxes, I believe) with the idea of observing which fields offered the best income opportunities so he could choose a well-paying career. I think he came to see that he liked accounting and was good at it, so there was no point in changing from that. He worked for a number of years at various small firms, then went solo as a one-man operation, which was not what he had in mind when he was in his twenties. You may find that there are opportunities for you in the U.S. beyond the world of large corporations.
Perhaps you can arrange for your father to fund your education while you live independently. You may have to work to provide for some living expenses, but that could be a good thing overall.
To make the decision, you’ll need to list and consider the pros and cons of each alternative, then prioritize them. One way to approach this is to make a matrix of all the key aspects, then compare each. For example, which is more important to you – U.S. citizenship or seeing your friends back home? Seeing your friends or getting a masters degree? Getting a masters degree or U.S. citizenship? And so on. By considering each pair of aspects and ranking them in this way, you can form a picture of which aspects really matter most to you, then see which path satifies more of them.
